Parallel beam of light of wavelength 500nm falls on two

Last updated: 6/10/2023

Parallel beam of light of wavelength 500nm falls on two narrow slits placed a distance d 25 x 10 4 cm apart at an angle 30 relative to the slits On the lower slit a transparent material 15 10 3 cm wide is placed Its refractive index is 7 The interference pattern appears on a screen a distance from the slits d O 30 The angular position of central maximum is 30 below certain line The order of minima closest to 8 0 is 26 Screen If the transparent material from the lower slits is removed then number of maximas that will pass through 8 0 position on screen is 50 If the transparent material from the lower slits is removed then number of maximas that will pass through 8 0 position on screen is 25 D
