Light & EM Waves
Is light a wave or a particle?
Both
White light is made up of what?
All of the colors combined
When a wave hits a solid object it bounces back. What is this called?
Reflection
Sound is an example of what type of wave?
Longitudinal
Electromagnetic waves differ in what two properties?
Frequency and wavelength
What are the colors in their correct order
Red Orange Yellow Green Blue Indigo and Violet
This type of waves moves perpendicular to the direction of the wave.
Transverse Wave
If two waves collide and the resulting wave is smaller what kind of interference happened?
Destructive.
Waves with the longest wavelengths are called
Radio waves
The primary colors of light are what three colors
The speed of a wave is calculated by multiplying what?
wavelength x frequency
Sonar sends sound waves to the bottom of the ocean. How is it able to measure where an bottom is?
The time it takes for the sound wave to hit the bottom and bounce back.
Waves with the shortest wavelengths are called
Gamma rays
The primary colors of pigments are
Cyan, Yellow and Magenta. They combine to form black.
This type of wave moves parallel to the direction of the wave.
Longitudinal wave
Does sound travel faster in metal or air?
Metal
If you are not able to see through an object it is said to be
Opaque
What is the correct sequence from from least see-through to most see-through.
Opaque-->Translucent-->Transparent
The length of time it takes one complete wavelength to pass a fixed point.
The effect you get when an ambulance passes you and the sound changes.
Doppler effect
