Wave Motion

Question 1

Progressive Wave

Answer 1

A progressive wave is one that transfers energy from one point to another without the transfer of matter

Question 2

Phase Angle

Answer 2

Phase (or phase angle) of a wave gives a measure of the fraction of a cycle that has been completed by an oscillating particle or by a wave

Question 3

Phase Difference

Answer 3

Phase difference between two particles in a wave or between two waves at a point is a measure of the fraction of a cycle which one is ahead of the other

Question 4

Wavefront

Answer 4

Wavefront is a line or surface joining points on a wave that are in phase

The wave travels in a direction that is perpendicular to the wavefront

Question 5

Polarisation

Answer 5

Polarisation is a phenomenon whereby the oscillations of transverse waves are restricted to a single plane
