A
Light is a set of particles

B
Light is a set of waves

C
Light is schizophrenic i.e. sometimes it behaves like a particle and other times like a wave.

D
Both particle and wave approaches help us understand different phenomenon

Solution

Light is an electro magnetic wave, it has dual nature and behave as both particle and wave
Question 2
1 / -0

A ray is an imaginary

A
line along the direction at an angle to the travel of the wave

B
line along the direction perpendicular to travel of the wave

C
line along the direction of travel of the wave

D
line from source to horizon

Solution

the direction or path along which,light energy travels in medium is called ray of light .
rays are the arrows perpendicular to the wavefront in direction of propagation of a wave.
