Waves

Question 1

Stationary wave

Answer 1

Wave pattern formed with nodes and antinodes formed when two or more progressive waves with same freq and amplitude pass through each other

Question 2

Longitudinal waves

Answer 2

Direction of vibration of particles is parallel to the direction in which the wave travels

Question 3

Transverse waves

Answer 3

The direction of vibration is perpendicular to the direction in which the wave travels

Question 4

Wavelength

Answer 4

Distance of one point in a wave to the respective adjacent point.

Question 5

Superposition

Answer 5

The effect of two waves adding together when meeting

Question 6

Period

Answer 6

Time for one complete wave

Question 7

Path difference

Answer 7

The difference in distances from two coherent sources to an interference fringe.

Question 8

Phase difference

Answer 8

The fraction of a cycle between the vibration of two vibrating particles.

Question 9

Node

Answer 9

Point in a stationary wave where amplitude is 0

Question 10

Frequency

Answer 10

Number of cycles of a wave that pass a point per second

Question 11

First harmonic

Answer 11

Pattern of stationary wave on a string where it vibrates at lowest possible frequency
