Question

For the same angle of incidence in media P, Q and
R, the angle of refraction is 45, 35 and 15 degrees
respectively. In which medium will the velocity of
light be minimum? Justify your answer

Answer 1

Answer:

Explanation:

           we know that sini = n sinr , here sini is const

         so, n is inversely related to sinr

                      and n = vel. of light in air / in medium

         n is inversely related to speed of light in medium

        so, sin r is directly related to speed of light in air

            so , in p speed is max

                   in r speed is min

   hope u get it n let me know.........................
