Question

i want Laser beam and soap water complete practical.

Answer 1

Answer:

if we pass laser beam which is a form of light, we will not be able to see that light travels in a straight line. but if we add some soap in it (a very little amount in the starting), we will see a little path of light. but if we add a bit more, than we will clearly see the path of light. hope it helps :)

if it helps than please mark me the breanleast if
