Light and Its Properties
What are the primary colors of light?
Red, blue, and green
What is reflection?
When light bounces off a surface, like a mirror.
How does light travel?
Fast and in a straight line until it hits something.
What is white light made of?
A mix of all colors of light.
Do refracted and transmitted mean the same thing?
No, refracted and transmitted do not mean the same thing.
What happens when light hits an object?
It can be reflected, absorbed, transmitted, or refracted
What is refraction?
The bending of light as it passes through a different material, like water or a prism.
What type of wave is light?
An electromagnetic wave.
What tool can separate white light into a rainbow?
A prism.
Why does the sky appear orange, pink, or purple at sunrise and sunset?
The sunlight travels through more atmosphere
How does light interact with transparent objects?
Light passes through them.
What happens when light is absorbed by an object?
It is taken in and can be converted into heat.
What are mechanical waves?
Waves that require a medium (like air, water, or solids) to travel through.
What is refraction in the context of a prism?
The bending of light, which separates it into different colors.
How does the atmosphere affect sunlight?
It changes the color and brightness of light.
What happens when all colors of light combine?
They form white light.
Why do black objects get hotter in sunlight?
They absorb all colors of light and convert it into heat.
Which color of light has the shortest wavelength?
Violet
Why do different colors bend at different angles in a prism?
Because each color has a different wavelength.
What is frequency in a wave?
The number of waves in a given time.
What does a blue object do with light?
It reflects blue light and absorbs red and green light.
What does the law of reflection state?
The angle of the incoming light equals the angle of the reflected light.
What happens to the energy of a wave as its frequency increases?
Higher frequency means more energy.
What happens when all the colors of light mix together quickly?
They appear as white light.
What is the relationship between wavelength and frequency?
Longer wavelength = lower frequency
