What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another, caused by a change in its speed.

Front

What is destructive interference?

Back

Destructive interference occurs when two waves meet and combine to produce a wave of lesser amplitude, often canceling each other out.

Front

How do you calculate the frequency of a wave?

Back

Frequency (f) can be calculated using the formula: f = velocity (v) / wavelength (λ).

Front

What is reflection in the context of waves?

Back

Reflection is the bouncing back of a wave when it hits a barrier or surface.

Front

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

Back

Velocity (v) can be calculated using the formula: v = frequency (f) x wavelength (λ).

Front

What is the relationship between wavelength and frequency?

Back

Wavelength and frequency are inversely related; as the wavelength increases, the frequency decreases, and vice versa.

Front

What is constructive interference?

Back

Constructive interference occurs when two waves meet and combine to produce a wave of greater amplitude.

Front

What is the speed of sound in air at room temperature?

Back

The speed of sound in air at room temperature is approximately 343 m/s.

Front

What is diffraction?

Back

Diffraction is the bending of waves around obstacles and the spreading out of waves when they pass through small openings.

Front

What is the principle of superposition?

Back

The principle of superposition states that when two or more waves overlap, the resulting wave displacement is the sum of the individual displacements.
