A circular disc of mass 5kg and diameter 0.2m initially at rest attains a angular velocity of 600rpm in 10 sec. Calculate the torque acting on it and the rate at which work is being done at the end of 10 sec
Optics
A ray of Light at an angle of 60 degree on one face of a prism angle 30 degree. The ray emerging out of the prism makes an angle of 30 degree with the incident ray. Calculate the refractive index of the material of the prism.

when you use the formula Nh=25cm/f, and your eye loses some ability of accomodation, will the Nh become bigger or smaller?

what is the way of propagation of light or any electromagnetic radiation? wheather it is streight linear flow of photon particles or wave propagation of energy or particle photon and wave phenomenon are simultaneous such that photon itself travel along the wave trajectory? please answer me as earlier as possible.

1.Why does dispersion occurs in case of the glass prism but not in case of a rectangular glass slab?
2. We know that during refraction the frequency of the light remains constant . Then in case of a mono-
chromatic light its frequency remains constant but the wavelength change. We know that for a particula
colour there is a particular wavelength range. Then if the wavelength change then how we get the same colour in case of dispersion or refraction
