light of wavelength 5.0 x 10 ^-7 meter in air hits a double slit. Distance between slits is 4.0 x 10^-4 m Distance to screen is 2.0 m
Calculate distance between two adjacent bright fringes on screen
Entire double slit apparatus is submerged in water which has index of refraction 1.3
Determine wavelength of light in water and it's frequency. Is distance between fringes on screen increased, decreased or remains same. Explain.
