Waves Test 2024 dec- A

Front

What is the formula for the speed of a wave?

Back

Speed = Wavelength × Frequency

Front

What is frequency in the context of waves?

Back

Frequency is the number of waves that pass a point in one second, measured in Hertz (Hz).

Front

What type of wave is characterized by oscillations perpendicular to the direction of wave travel?

Back

Transverse Wave.

Front

How do you calculate the velocity of a wave?

Back

Velocity = Wavelength × Frequency.

Front

What happens to a wave when it reflects off a surface?

Back

The wave bounces back, which is known as reflection.

Front

What is the unit of measurement for wavelength?

Back

Meters (m).

Front

If a wave has a frequency of 10 Hz and a wavelength of 2 meters, what is its velocity?

Back

Velocity = 10 Hz × 2 m = 20 m/s.

Front

What is the difference between transverse and compressional waves?

Back

Transverse waves oscillate perpendicular to the direction of travel, while compressional waves oscillate parallel to the direction of travel.

Front

What is constructive interference?

Back

Constructive interference occurs when two waves meet and combine to make a wave with a larger amplitude.

Front

What is destructive interference?

Back

Destructive interference occurs when two waves meet and combine to make a wave with a smaller amplitude.
