Facts
Why do you see lightning before you hear thunder?
Light travels much faster than sound.
What happens to light when it bounces off a surface?
Reflection
When light bends as it hits an object.
When you are facing falling rain with the sun behind you. What do you see?
A rainbow
What are primary colors?
RBG. Red Blue Green
Why is the sky blue?
Blue light scatters more than other colors in the atmosphere.
What is true about the angle of reflected light compared to the angle of incoming light?
They are equal
The angle between the ray and the normal on the other side of the boundary
Angle of refraction
Splitting white light into separate colors.
Dispersion
How do we make secondary colors?
Two primary colors combined form a secondary color.
Why does a swimming pool look shallower than it really is?
Refraction
If you shine a flashlight at a mirror, where does the light go?
It reflects off the mirror.
Light bends when it travels from air into what?
Water (or any other object)
What is actually being separated when a prism creates a rainbow?
White light
This is something that is absorbs some colors of light and transmits others.
Filter
The angle at which light hits a mirror is called what?
The angle of incidence
Does light bend because its speed changes or because its color changes?
The speed changes
A triangular piece of glass that light can shine into
Prism
If you can see a red T shirt, what colors are being absorbed?
The red shirt is absorbing all of the colors in white light except red. Red light is reflected into our eyes when we see a red shirt.
Speed of light in an empty space / speed of light in the medium.
Refractive index
When the incident ray hits the side of the prism at a particular angle, the light emerging from the prism is split into colors called?
Spectrum
A tomato appears red. Is it actually reflecting red or absorbing red?
