Waves Review - 2nd

Front

What type of electromagnetic wave has the highest frequency?

Back

Gamma rays emitted by radioactive materials.

Front

Which type of wave diagram most likely represents radio waves?

Back

The longest wave.

Front

Why does a porpoise hear its echo first when both it and a bat produce ultrasonic waves at the same distance from an object?

Back

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

Front

What must be measured 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

How did the observation of uranium salts reacting under black paper affect students' beliefs about light?

Back

The students had to revise their earlier belief because evidence from the experiment did not support the original conclusion.

Front

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

Back

Sound travels slower in air than in water.

Front

What are the three main types of electromagnetic waves in the spectrum?

Back

Radio waves, visible light, and gamma rays.

Front

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

Back

As the wavelength increases, the frequency decreases, and vice versa.

Front

What is the principle behind sonar technology used by porpoises?

Back

Sonar technology relies on the reflection of sound waves to locate objects.

Front

What is the significance of the speed of sound in different mediums?

Back

The speed of sound varies in different mediums, affecting how quickly sound can be heard.
