The number of wave cycles per unit of time

The amount of time of one wave cycle

The length of one wave crest to another crest

The drawing shows two waves. Which statement best compares these two waves?

Wave 2 has more energy because it has a higher amplitude than wave 1.

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 frequency than wave 1.

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

Waves spread out from an earthquake through the Earth. Based on the photo, which of these is true?

The waves bend as they move from one layer to another.

The waves travel in a straight line through the Earth.

P waves travel slower than S waves.

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 higher frequency.

The light wave would have a lower 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.

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 lower pitched as it drives away.

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.

Why can't two radio stations broadcast at the same frequency in the same area?

Because waves at the same frequency will create interference.

Because radio waves don't travel as far as other types of electromagnetic waves.

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?

Microwave or infrared, because they travel better than light but carry more data than radio.

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.

Identify which end of the electromagnetic spectrum has the Longest Wavelength and Shortest Wavelength.

Shortest - Gamma; Longest - Radio

Longest- Gamma; Shortest- Radio

Shortest - Microwaves; Longest - Ultraviolet

Explain why a black car looks black to our eyes.

it is absorbing all colors of light

it is reflecting all colors of light

Explain why a white car looks white to our eyes.

it is reflecting all colors of light

it is reflecting blue light and absorbing all others

it is absorbing all colors of light

Explain the difference between reflection and absorption of light waves.

reflection is when light waves bounce off an object; absorption is when light waves are taken in

reflection is when light waves are taken in; absorption is when light waves bounce off an object

reflection is when light waves bounce off an object; absorption is when light waves travel through an object

reflection is when light waves travel through an object taken in; absorption is when light waves are taken in

A: refraction B: absorption C: reflection

A: reflection B: absorption C: refraction

A: absorption B: refraction C: reflection

A: refraction B: reflection C: absorption
