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.
Draw the final image formed by two lenses: An optical imaging system consists of two positive lenses (L1 and L2). L1 has a focal length f 1 = 10 cm, and L2 has a focal length
