In the above figure light is reflected from the concave mirror,and in reflection-
1.Frequency
2.Wavelength and
3.Velocity of ray of light
All the above three parameters remain same.But the factor which gets changed on reflection,is intensity of light.It is found that intensity of reflected light in not equal to that of incident light,because some of the light is absorbed by the mirror.Thus option (1).intensity of light gets changed,
