IGCSE Properties of Wave

What is the definition for the word amplitude?

• The number of complete waves that pass per second

• The distance from the peak of one wave to the peak of an adjacent wave.

• The distance from the equilibrium position of a peak plus the same distance from a trough.

• The maximum distance from the equilibrium position of any point on a wave

what is the name given to the effect that allows wavefronts to reach point X, shown in the diagram?

Which 2 points on the wave are exactly one wavelength apart?

• P and S

• Q and R

• Q and S

• P and R

Water waves travel from deeper water to more shallow water. This causes them to refract.

Which property always remains the same when refraction occurs?

• Wavelength

• Frequency

• Amplitude

• Speed

• A

• B

• C

• D

what is the formula for finding the wavelength of a wave?

• v = f λ

• λ / v = f

• v f = λ

• λ / f = v

• A

• B

• C

• D

• It doubles

• It halves

• It remains the same

• It becomes four times as large

• The speed of wave increases.

• The speed of wave decreases.

• The frequency increases.

• The frequency decreases.

• Decrease the speed of waves (but keep the wavelength the same).

• Increase the speed of the waves (but keep the wavelength the same).

• Make the gap smaller

• Make the gap bigger
