a) Maximum for red light
b) Maximum for blue light
c) Maximum for white light
d) Same for all lights​

Answer 1

Answer:

maximum for red light

it is your answer

Answer 2

Answer:

The "focal length of spherical mirror" is same for all the lights.

Explanation:

• Light as we know it different Shades present in it that make one complete light these shades of light scatter within the medium where the speed of the wavelength of the front light changes, but in case of mirror these shades of light scatter within the medium where the speed of the wavelength of different light changes but in case of mirror be it spherical or plane mirror.
• The light falling on it is completely reflected back so the different wavelengths doesn't matter because it is just reflecting them hence the light will be intact.
