Waves

Question 1

State the principle of superposition of waves

Answer 1

When 2 waves meet, The total displacement at a point is equal to the sum of the individual displacements at that Point.

Question 2

State the definition of longitudinal waves

Answer 2

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

Question 3

State the definition of transverse waves

Answer 3

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

Question 4

State the definition of plane polarised Wave

Answer 4

Waves where vibrations stay in one plane only

Question 5

State the definition of displacement

Answer 5

The distance and direction of a vibrating particles from its equilibrium position

Question 6

State the definition of amplitude

Answer 6

Maximum displacement of a vibrating particle

Question 7

State the definition of wavelength

Answer 7

Least distance between two adjacent vibrating particles with the same displacement and velocity at the same time
