The drawing shows two waves. Which statement best compares these two waves?
Wave 1 has a higher frequency because it has a longer wavelength than wave 2.
Wave 1 has a higher frequency because it has a higher amplitude than wave 2.
Wave 2 has more energy because it has a higher amplitude than wave 1.
Wave 2 has more energy because it has a higher frequency than wave 1.
Which color of light has the highest energy of this group?
red
yellow
green
purple
What is the Doppler Effect?
A change in frequency due to the relative motion of a wave source and an observer
When a wave overlaps with another wave
When a wave bounces off of another object
When a wave bends due to traveling through a different medium
An astronomer looks at a star in the night sky. Based on his calculations the star's light is shifting towards the color blue. What does this mean about the star?
It's moving towards the astronomer
It's moving away from the astronomer
It's not moving at all
Look at the picture. Who is experiencing a higher pitched sound?
Observer A
Observer B
There's no difference
Look at the picture. Who is experiencing a lower pitched sound?
Observer A
Observer B
There is no difference
The number of wavelengths that pass a point per second is:
frequency
period
longitudinal
transverse wave
Waves travel in a straight line until they enter a different substance, or "medium." What happens when they enter a different medium?
They keep going in a straight line at the same speed
They change speed but do not refract
They refract but never change speed
They refract and change speed
Waves spread out from an earthquake through the Earth. Based on the photo, which of these is true?
The waves travel in a straight line through the Earth.
P waves travel slower than S waves.
The waves bend as they move from one layer to another.
The waves only travel around the outside of the Earth, not through the core.
Light waves move at a much higher velocity compared to sound waves. If a light wave and a sound wave had the same wavelength, which of these is true?
The light wave would have a lower frequency.
The light wave would have a higher frequency.
Because they have the same wavelength, they have the same frequency.
Because they move at different velocity, they can't have the same wavelength.
Two sound waves have different frequencies. The wave with the higher frequency...
Moves through the air faster.
Is louder.
Is higher pitched.
Sounds exactly the same.
Two strings on a harp are made of the same kind of wire. One string is long and one is short. Which string will make a higher pitch sound?
The short string, because a shorter wavelength means a higher frequency.
The long string, because a longer wavelength means a higher frequency.
The short string, because shorter waves travel faster.
The long string, because longer waves travel faster.
An ambulance drives past you on the street. As it goes by you, the sound of the siren changes. What is the best explanation of the change?
The siren will get louder as it drives away.
The siren will get quieter as it gets close to you.
The siren will get higher pitched as it drives away.
The siren will get lower pitched as it drives away.
Why can't two radio stations broadcast at the same frequency in the same area?
Because radio waves don't travel as far as other types of electromagnetic waves.
Because waves at the same frequency will create interference.
Because waves at the same frequency will make the signal too strong and it is dangerous.
They can. All radio waves are the same frequency.
For a wi-fi network you want waves that can travel a short distance, are safe for humans to be around, and carry a lot of data fast. What would be the best kind of wave?
Ultra short waves like x-rays, because they carry the most data.
Ultra long waves like low frequency radio, because long waves carry more data.
Light waves because there is already a lot of light in your home.
Microwave or infrared, because they travel better than light but carry more data than radio.
