what will be the effect on the fringes, if young's double slit experiment set up is immersed in water?

Dear student
Wavelength of light in water is less than that in air. The fringe width is directly proportional to the wavelength. Therefore, the fringes will become narrower.

If the young's double slit experiment set-up is immersed in water, then the fringes become narrower. You have learnt in the text how Huygens' principle leads to the laws of reflection and refraction. The reflected wavefront AB'C, appears to start from I. Hence, I becomes virtual image for O as real point object.

The length of a massless rod is measured using vernier callipers having 10 vernier scale divisions and least count of 0.1 mm. Two masses 1.00 ± 0.01 kg and 4.00 ± 0.02 kg are attached to its ends. If reading of vernier scale is 5 divisions coinciding with 1.3 cm, what is the % error in locating centre of mass from lighter mass
