Waves Review - 1st

Front

Where is VISIBLE light located in the Electromagnetic Spectrum?

Back

In the middle of the spectrum.

Front

Which animal would hear its echo first when both produce ultrasonic waves at a distance of 16 meters from an object, a porpoise or a bat?

Back

The porpoise would hear its echo first because sound travels faster in water than in air.

Front

What is the process called when light waves change direction as they pass from one medium to another?

Back

Refraction.

Front

Which type of wave is represented by the longest wave in a graph of electromagnetic waves?

Back

Radio waves.

Front

What do you need to measure to prove that sound travels faster through solids than through liquids or gases?

Back

The time required for sound to travel a set distance through a solid, a liquid, and a gas.

Front

What is the speed of sound in air compared to its speed in water?

Back

Sound travels slower in air than in water.

Front

What is the range of the electromagnetic spectrum that is visible to the human eye?

Back

Approximately 400 to 700 nanometers.

Front

What is the relationship between wavelength and frequency in electromagnetic waves?

Back

They are inversely related; as wavelength increases, frequency decreases.

Front

What type of wave is sound classified as?

Back

A mechanical wave.

Front

What is the phenomenon called when sound waves bend around obstacles?

Back

Diffraction.
