Mechanical waves require which of the following to travel?

• A medium

• A vacuum

• A force

What is the equation for wave speed?

• wave speed (m/s) = frequency (Hz) x wavelength (m)

• wave speed (m/s) = distance (m) / time (s)

• wave speed (m/s) = amplitude (m) x frequency (Hz)

• wave speed (m/s) = period (s) / frequency (Hz)

What is the unit of frequency?

What is the term for the maximum displacement of a point on a wave from its undisturbed position?

What is the phenomenon called when waves bounce back after hitting a surface?

What is the term for the change in direction of waves as they pass from one medium to another?

The relationship between period (T) and frequency (f) is given by T = (a)  

• 1 / f
• f
• T * f
• T + f

What is the term for the energy of the waves being transferred to the energy stores of the substance they travel into?

What is the term for the distance from one point on a wave to the equivalent point on the next wave?

What is the term for the time taken for one complete wave to pass a fixed point?
