Unit 7 Waves (2024)

Front

What is the formula to calculate wavelength?

Back

Wavelength (λ) = Wave Speed (v) / Frequency (f)

Front

Define wavelength in the context of waves.

Back

Wavelength is the distance between successive crests or troughs of a wave.

Front

What is the relationship between frequency and period?

Back

Frequency (f) is the reciprocal of the period (T): f = 1/T.

Front

What is diffraction in wave behavior?

Back

Diffraction is the bending and spreading of waves when they pass through an opening or around obstacles.

Front

What is a transverse wave?

Back

A transverse wave is a wave in which the particle displacement is perpendicular to the direction of wave propagation.

Front

What is a trough in a wave?

Back

The trough is the lowest point of a transverse wave.

Front

How do you calculate the period of a wave?

Back

Period (T) = 1 / Frequency (f).

Front

What is the speed of a wave?

Back

Wave speed (v) is the distance traveled by a wave per unit time, calculated as v = λ * f.

Front

What is the significance of nodes and antinodes in waves?

Back

Nodes are points of no displacement, while antinodes are points of maximum displacement in standing waves.

Front

How do you determine the time delay of a reflected sound wave?

Back

Time delay = Distance / Velocity. For a distance of 500 m and velocity of 352 m/s, Time delay = 500 m / 352 m/s.
