Question

If youngs apparatus is immersed in water then fringe width will

Answer 1

Answer:

Answer:If the Young's apparatus is immersed in water, the effect on fringe width will. The wavelength of light is less in water than in air . Hence the fringe width will decrease. The interference pattern will be observed but the fringes will be narrower.

i hope this will help uhh

Answer 2

A perfectly elastic collision just means the total amount of kinetic energy is conserved. Further, Newton's laws tell us momentum must be conserved. Any velocity change following a collision is therefore dictated by the mass of the two bodies, their velocities and the application of those two conservation rules.
