Q1. A laser produces red light offrequency 4.7 x 10 14 Hz. The speedof light in glass is 2.0 x 10 8 m/s.(a) Calculate the wavelength in glassof light from this laser. |

Answer» frequency, f=4×10 14 Hz Wavelength, λ=5×10 −7 m velocity, v=fλ =4×10 14 ×5×10 −7
=20×10 7
v=2×10 m/s Refractive INDEX, μ= v c
= 2×10 8
3×10 8
μ=1.5. this type this question made |
