Sound, Waves and Light Flashcard

Front

What is the formula to calculate the velocity of a wave?

Back

Velocity (v) = Frequency (f) × Wavelength (λ)

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 is wavelength?

Back

Wavelength is the distance between two consecutive points in phase on a wave, such as crest to crest or trough to trough.

Front

What is a crest in a wave?

Back

A crest is the highest point of a wave.

Front

What is a trough in a wave?

Back

A trough is the lowest point of a wave.

Front

How does energy relate to wave amplitude?

Back

The energy of a wave is directly proportional to the square of its amplitude; higher amplitude means higher energy.

Front

What type of wave is sound?

Back

Sound is a longitudinal wave, where the particle displacement is parallel to the direction of wave propagation.

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, including radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.

Front

Which type of light has the highest energy?

Back

Ultraviolet light has higher energy than visible light.

Front

Which type of light has the lowest energy?

Back

Radio waves have the lowest energy in the electromagnetic spectrum.
