wave motion

In wave motion ..........

• (a) medium particles move

• ( b ) the waves moves carrying the energy

• ( c ) medium particles vibrate without transferring from their places

• ( b ) and ( c ) are correct

When hitting fork , the particles of air in touch with it .....................

• don't move

• Vibrate perpendicular to the direction of wave propagation

• vibrate in the direction of wave propagation with changing their places

• vibrate in the direction of wave propagation without changing their places

............. is ( are) mechanical waves

• water wave only

• Sound wave only

• Light wave only

• Sound wave and water wave

All of the following are electromagnetic waves except. ............ waves

• Light

• Sound

• Microwave

• Radio

Transverse waves consists of .............

• Compressions and rarefactions

• Troughs and rarefactions

• Crests and troughs

• Compressions and crest

Longitudinal waves consists of .............

• Compressions and rarefactions

• Troughs and rarefactions

• Crests and troughs

• Compressions and crest

All the following are transverse waves except ........... Waves

• Water

• Sound

• Light

• Radio

Sound waves are longitudinal waves , because the particles of medium ...............

• don't vibrate

• vibrate along the direction of waves propagation

• don't need medium to propagate through

• vibrate in a direction perpendicular to the direction of wave propagation

the highest point of the particles of the medium in the transverse wave is known as ..................

• the crest

• The compression

• The rarefaction

• The trough

the lowest point of the particles of the medium in the transverse wave is known as ..................

• the crest

• The compression

• The rarefaction

• The trough
