Question

What are the two main properties of light?

Answer 1

Answer:

Some of the properties of light are:

1. Light always tends to travels in straight line.
2. Light is made of electric and magnetic vectors that oscillate mutually perpendicular.
3. Direction of wave propagation is perpendicular to both electric and magnetic vectors.
4. It is made of photons. These photons have rest mass zero and they travel with a speed of 3 × 10^8 m/s.
5. It does not need material medium for propagation.
6. It is transverse in nature.
7. It shows the phenomena of reflection, refraction, diffraction and polarisation.
8. Light rays carry no charge and hence they don't deviate in electric and magnetic fields.
