Q. Why X-rays are not used in microscopes?
1) The wavelength of X-rays is slighter than that of the visible light.
2) X-rays can't be focussed as visible radiations are focussed using lenses.
3) X-rays can't be deflected by electric and magnetic fields.
Q. Illustrate what is curvilinear motion? Answer:- Fundamentally it's any motion that's formed or else bounded by curved as opposed to straight lines. In high school curvi
