Question
State four properties of electro magnetic waves.
✓
Answer
(i) They do not require any material medium to travel.
(ii) They are transverse in nature i.e., electric and magnetic fields are perpendicular to each other and also to the direction of the propagation of the wave.
(iii) The energy of the wave is divided equally amongst the electric and the magnetic field.
(iv) They travel, in free space, with a velocity of $3 \times 10^{8} ms^{-1}$.

Answer the following question:
virtual image, we always say, cannot be caught on a screen.
Yet when we 'see' a virtual image, we are obviously bringing it on to the 'screen' (i.e., the retina) of our eye. Is there a contradiction?
