Question

the refractive index of glass with respect to water is 9 divided by 8 if the velocity and wavelength of light and water are 2.25 into 10 power 8 M per second and 5400 Armstrong respectively find the velocity and wavelength of light in glass

Answer 1

velocity V = 2.25 x 10^8 m s -1
refractive index = 9 / 8
refractive index of Glass = speed of light in medium 1 / speed of light in medium 2

9 / 8 = 2.25 x 10^8 / speed of light in glass

therefore, speed of light in glass = 2 x 10^8 ms-1

refractive index of Glass = wavelength of light in medium 1 / wavelength of light in medium 2
9/8=5400/ wavelength of light in glass
therefore,wavelength of light in glass =4800 A

Answer 2

Answer:

velocity  V = 2.25 x 10^8 m s -1

wavelength of light in glass =4800 A

Explanation:

refractive index = 9 / 8

refractive index of Glass = speed of light in medium 1 / speed of light in medium 2

9 / 8 = 2.25 x 10^8 / speed of light in glass

therefore, speed of light in glass = 2 x 10^8 ms-1

refractive index of Glass = wavelength of light in medium 1 / wavelength of light in medium 2

9/8=5400/ wavelength of light in glass

therefore,wavelength of light in glass =4800 A
