Question

In a ydse a parallel beam of wavelegnth 6000 is incident on slits at angle of incident 30

Answer 1

Explanation:

In a YDSE a parallel beam of light of wavelength 6000Å is incident on slits at angle of incidence 30∘. A and B are two thin transparent films each of refractive index 1.5. thickness of A is 20.4μm. Light coming through A and B have intensities I and 4I resepctively on the screen.

Answer 2

Answer:

In a YDSE a parallel beam of light of wavelength 6000 Å is incident on slits at angle of incidence 30º. A & B are two thin transparent films each of refractive index 1.5. Thickness of A is 20.4 µm. Light coming through A & B have intensities I & 4I respectively on the screen.
