FLASHCARD QUESTION

Front

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

Back

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

2.

FLASHCARD QUESTION

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).

3.

FLASHCARD QUESTION

A crest is the highest point of a wave.

5.

FLASHCARD QUESTION

Front

What is a trough in a wave?

Back

A trough is the lowest point of a wave.

6.

FLASHCARD QUESTION

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.

7.

FLASHCARD QUESTION

Front
