Question 1

Transverse Wave

Answer 1

Medium particles vibrate in a direction perpendicular to the direction of wave propagation.

Question 2

Longitudinal Wave

Answer 2

Medium particles vibrate in a direction parallel to the direction of wave propagation

Question 3

Mechanical wave

Answer 3

requires a medium to transfer energy

Question 4

electromagnetic wave

Answer 4

does not require medium to tranfer energy

Question 5

Damping

Answer 5

decrease of the amplitude of an oscillating system due to energy loss

Question 6

Resonance

Answer 6

when periodic force is applied to the oscillating system at its natural frequency causing the system to osscilate with maximum amplitude.

Question 7

wavelength

Answer 7

distance between two conservative points in phase

Question 8

amplitude

Answer 8

maximum of displacement of a particle from its equillibrium position

Question 9

Frequency

Answer 9

number of complete oscillation in one second

Question 10

period

Answer 10

time taken by a particle to complete oscillation

Question 11

Refraction of Waves

Answer 11

change in direction of propogation of waves caused by the change in velocity of waves when the waves propogates from one medium to another.

Question 12

Diffraction

Answer 12

Waves spread when passing through an opening or around an obstacle

Question 13

Interference of waves

Answer 13

superposition of two or more waves from a coherent wave source

Question 14

Electromagnetic Waves

Answer 14

waves made up of an electric field and a magnetic field that oscillates perpendircularly to one another
