Answer #1

Refractive index of acrylic medium is given by

Angle of incidence is given as

Let refractive angle be "r", then using Snell's law:

  

  

  (ANS)

Hence, angle of the light with respect to the normal in the acrylic is,

Assume a satellite shines an unpolarized light on a telescope. The intensity of the light as it reaches the telescope is 1.1*10-10 W/m2 a lit, 1000-watt light bulb mounted on it. The unpolarized light from the light bulb, upon reaching the telescope, is passed through two polarizing filters that are at an angle of 30° with respect to each other, and then the resulting light is projected onto a CCD camera. What is the intensity of the light detected by...
