Understanding Waves and Energy

Front

What is a wave?

Back

A disturbance that transfers energy from place to place

Front

Which of the following is a type of mechanical wave?
Options: Electromagnetic wave, Transverse wave, Sound wave, Both B and C

Back

Transverse wave, Sound wave

Front

How does a transverse wave move through a medium?

Back

At right angles to the direction of the wave

Front

Calculate the speed of a wave with a wavelength of 2 meters and a frequency of 5 Hz.

Back

10 m/s

Front

What happens to a wave when it is absorbed by a medium?

Back

Its energy is transferred to the medium

Front

Explain why sound waves travel faster in liquids and solids than in air.

Back

Because liquids and solids are denser than air.

Front

Describe the process of refraction.

Back

When a wave enters a new medium at an angle and bends.

Front

What is the relationship between wavelength and frequency in determining the speed of a wave?

Back

Speed = wavelength * frequency

Front

How does diffraction affect a wave?

Back

It causes the wave to bend around barriers

Front

What is the law of reflection?

Back

The angle of incidence equals the angle of reflection
