Electromagnetic energy travels in waves. When we describe electromagnetic waves, we often talk about the wave’s length and frequency. Which of these statements accurately describes the relationship between the wavelength and frequency of an electromagnetic wave?
a)
If wavelength increases, frequency increases.
b)
If frequency decreases, wavelength increases.
c)
If frequency remains constant, wavelength increases.
d)
If wavelength remains constant, frequency increases.

He would have seen the lightning and heard the thunder at the same time.
b)
Sound travels faster than light.
c)
Light travels faster than sound.

pool
c)
oxygen
d)
lake

The light scatters.
b)
The light is absorbed.
c)
The different colors of light are bent at different angles due to their speeds.

True
b)
False
c)
Only on Mars
d)

a)
purple light(violet)
b)
orange light
c)
red light
d)
not light has energy
19.
When you are at a basketball game, what happens to the sound waves coming from the mouths of many people?
a)
Destructive interference. Each wave takes energy away from the sounds it combines with.
b)
Constructive interference: the waves "add" together to make a louder wave.
c)
James Benson's waves take over all other waves.
d)
The waves refract with each other and fall apart.
20.
Waves with more energy are more damaging to humans. What are the 3 wave properties that give a wave more energy?
