How do you Make Shadows with 3 different colored lights?
With these three coloured lights you can make shadows of seven different colours: blue, red, green, black, cyan (blue-green), magenta (pink), and yellow. If you block two of the three lights, you get a shadow of the third color. block the red and green lights and you get a blue shadow. block all three lights, you get a black shadow.
What happens if you block all the lights in a shadow?
If you block only one of the lights, you get a shadow whose color is a mixture of the other two. Block the red light and the blue and green light mix to create cyan; block the green light and the red and blue light make magenta; block the blue light and red and green make yellow. If you block all three lights, you get a black shadow.
What are the colors of the shadows cast by an object that is placed under blue and red lights only?
What are the colors of the shadows cast by an object that is placed under blue and red lights only? The red light casts a blue shadow and the blue light casts a red shadow, because the space not illuminated by red is illuminated by blue, and vice versa.
What is the resulting color if equal intensities of red light and cyan light are combined?

What is the effect on the color of a cloud when it contains an abundance of large droplets?
When a cloud contains large droplets, it will scatter lower frequency light. Thus, the cloud will appear reddish.
What happens when red, green, and blue light are mixed?

What is the effect on the color of a cloud when it contains an abundance of large droplets quizlet?
Water droplets of different sizes scatter a variety of light frequencies, resulting in a white cloud. What is the effect on the color of a cloud when it contains an abundance of large droplets? The cloud becomes dark.
Is blue light high or low frequency?
Blue light has shorter waves, with wavelengths between about 450 and 495 nanometers. Red light has longer waves, with wavelengths around 620 to 750 nm. Blue light has a higher frequency and carries more energy than red light.
What happens to light of a certain frequency when it is incident upon a material whose natural frequency is the same as the frequency of the light?
If a light wave of a given frequency strikes a material with electrons having the same vibrational frequencies, then those electrons will absorb the energy of the light wave and transform it into vibrational motion.
What color do you get when you block three lights?

What colors do green filtered flashlights have?
The green-filtered flashlight puts out yellow, green and blue wavelengths. The blue-filtered flashlight puts out green, blue, and purple wavelengths. When the three coloured light bulbs all shine on the same surface, we see all the wavelengths from red through to purple, which we perceive as white. With these three coloured lights you can make ...
What color do green cones pick up?
Green cones will pick up purple, blue, green, yellow, and orange hues. Red cones will pick up purple, blue, green, yellow, orange, and red hues (see diagram below). The sensitivities of the three cones overlap to let us perceive all visible colours.
Why do we see sunlight as white light?
This is why we see sunlight as white light, not as its individual colours. Slight changes in the relative signals of the cones enable us to see a myriad of different colour combinations, which is why we "see" more than just three colours.
What is the spectrum of light?
Light is a continuous spectrum of all of the wavelengths that can be detected by the human eye. However, the human eye normally contains only three types of colour ranges of the colour spectrum. Humans and other species with three such types of color receptors are known as trichromats.
How many shadows does a green light block?
And when you hold an object in front of the screen, you will see two shadows, one blue and one green. In one place, the object blocks the light coming from the green bulb, leaving a blue shadow; in the other location it blocks the light from the blue bulb, leaving a green shadow.
What are the colors of shadows?
With these three lights you can make shadows of seven different colors—blue, red, green, black, cyan, magenta, and yellow— by blocking different combinations of lights (click to enlarge diagram below).
Why does a screen look white?
When a red light, a blue light, and a green light are all shining on the screen, the screen looks white because these three colored lights stimulate all three types of cones in your eyes approximately equally, creating the sensation of white. Red, green, and blue are therefore called additive primaries of light.
What color is the screen when you turn off the green light?
The shadows will be red and blue. When you turn off the blue light, leaving on the red and green lights, the screen will appear to be yellow. The shadows will be red and green.
How many patches of light can you see on a card?
Going Further. If you let light from the three bulbs shine through a hole in a card that is held an appropriate distance from the screen, you will see three separate patches of colored light on the screen, one from each lamp. (Make the hole large enough to get a patch of color you can really see.)
What lightbulbs can be used at the same time?
Red, green, and blue lightbulbs. A way to plug in all three lightbulbs at the same time and simultaneously direct their light onto the same white surface. A white surface, such as a wall or a piece of white poster board (white paper taped to stiff cardboard also works well)
How to make cyan with blue and green?
Block the red light and the blue and green light mix to create cyan; block the green light and the red and blue light make magenta; block the blue light and red and green make yellow. If you block all three lights, you get a black shadow. You can achieve a similar effect by turning off different lightbulbs.

Maybe these decisions from the USGA website "Rules and Decisions" will be helpful: http://www.usga.org/Rule-Books/Rules-of-Golf/Rule-01/ [b]Decision 16-2/3 Casting Shadow on Ball Overhanging Hole [/b] Q. A player's ball came to rest overhanging the edge of the hole.

You are allowed 10 seconds to wait for the ball to drop. Do you really think your shadow is going to have any effect on the grass in 10 seconds? Seriously??

Q. A player's ball came to rest overhanging the edge of the hole. The player walked up to the hole and cast his shadow on the ball, believing that this would cause the grass to wilt and his ball to fall into the hole. Was the player in breach of Rule 1-2 (Exerting Influence on Ball) when he cast his shadow on the ball?

I had one of those putts last Saturday, one I have never seen before. It did at least a 360 around the cup, I swear it was almost 1/2 below the edge as it went around, then popped out and hung over the edge with at least 1/3 of the ball hanging over the cup.
Newby
Ok, your ball comes to rest on the very very edge of the hole. As the theory goes if you put your shadow over the ball and grass area the grass relaxes and bends allowing the ball to move and sometimes if the ball is close enough it will move into the hole.

I've seen it work once or twice, but you always wonder: Would it have dropped in at that same moment anyway or did the shadow actually make the ball drop? I'm a believer, but the conditions have to be perfect for it to work.
