IGCSE - General wave properties

What is the correct formula for wave speed?

• Wave speed = frequency x wavelength

• Wave speed = amplitude x wavelength

• Wave speed = amplitude x period

• Wave speed = frequency x period

The highest point on a transverse wave is the

• compression

• crest

• rest position

• trough

The lowest point on a transverse wave is the

• compression

• crest

• rest position

• trough

The number of waves that pass somewhere in a second is:

• amplitude

• frequency

• wavelength

#1 refers to the

• wavelength

• amplitude

• crest

• trough

#2 refers to the

• wavelength

• amplitude

• crest

• trough

#3 refers to the

• wavelength

• amplitude

• crest

• trough

#4 refers to the

• wavelength

• amplitude

• crest

• trough

Longitudinal waves have:

• crests and troughs

• crests and compressions

• compressions and rarefactions

• troughs and rarefactions

Transverse waves have:

• crests and troughs

• troughs and rarefactions

• compressions and contractions

• rarefactions and crests
