IGCSE Waves

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 unit for wavelength?

What is the unit for frequency?

What is the unit for velocity?

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

• v = f λ

• λ / v = f

• v f = λ

• λ / f = v
