Test 3: Complete Chapter – Concepts, Numericals and Details

Question 1

The amplitude of a wave is the maximum displacement of a point on the wave from its:

• Aundisturbed (rest) position
• Bcrest
• Ctrough
• Dwave front

Question 2

The wavelength is the distance between two corresponding points on adjacent waves, for example:

• Acrest to crest or trough to trough
• Bcrest to trough
• Ccompression to rarefaction only
• Drest position to crest

Question 3

The SI unit of wavelength is:

• Ahertz
• Bsecond
• Cmetre (m)
• Dmetre per second

Question 4

The wave period is measured in:

• Ahertz
• Bseconds (s)
• Cmetres
• Dm s⁻¹

Question 5

An FM radio station called 88.0 MHz is sending:

• A88 thousand wave cycles per second
• B88 million wave cycles per second
• C88 wave cycles per second
• D88 billion wave cycles per second
