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.
Points O, A, and P lie in one as well as the same vertical plane. Point A is 4 . 0 cm due east of point O starting at point O one is able to arrive at point P by going 6 . 0 cm due
