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. |
