A monochromatic light of wavelength 560 nm is incident on a single sli – InterviewSolution

1.	A monochromatic light of wavelength 560 nm is incident on a single slit and a diffraction pattern is formed. Now the whole set up is placed in liquid of refractive index 1.5 and when in this case a light of wavelength λ is used the third maxima coincides with 2nd minimum of previous case. The wavelength λ of light is
Answer» A monochromatic light of wavelength $560 nm$ is incident on a single slit and a diffraction pattern is formed. Now the whole set up is placed in liquid of refractive index $1.5$ and when in this case a light of wavelength $λ$ is used the third maxima coincides with $2^{n d}$ minimum of previous case. The wavelength $λ$ of light is
