★ PROPERTIES OF LIGHT
Light travels in straight line.
It is made of electric and magnetic vectors that oscillate mutually perpendicular.
Direction of wave propagation is perpendicular to both electric and magnetic vectors.
It is made of photons. These photons have rest mass zero and they travel with a speed of 3 × 10^8 m/s.
It does not need material medium for propagation.
It is transverse in nature.
It shows the phenomena of reflection, refraction, diffraction and polarisation.
Light rays carry no charge and hence they don't deviate in electric and magnetic fields.
Energy possessed by each photon is E = hf where h is Plank's constant ( 6.6 × 10^-34 Js) and f is frequency.
On passing through prism it separates into constituent colours and what we obtain is called spectrum ( VIBGYOR).

light is electromagnetic radiation that has properties of waves the electromagnetic spectrum can be divided into several bands based on the wavelength as we have discussed before, visible lights represent a narrow group of wavelengths between about 380nm and 730nm.
