The two spreed of light on glasss in 2× 10 ^5 what is the ri of glass​

Answer»

Answer:

The speed of LIGHT in AIR is c = 3 × 108 m/s.

Thus, the speed of light in GLASS will be given as.

v = c/n = 3 × 108/ 1.5 = 2 × 108 m/s.

The speed, wavelength and frequency are related as.

c = νλ

Thus, wavelength in air is given as.

λa = c/ν = 3 × 108/ 6 × 1014 = 5 × 10-7 m.
