Question

Write four basic properties of electromagnetic waves

Answer 1

- Travel in a vacuum with a speed of 3.0x108m/s.

- Do not require material medium for their propagation.

- Transverse in nature.

- Posses and transfer energy. The amount of energy possessed by an electromagnetic wave of frequency f  is expressed as E= hf, where h is Plank’s constant and is equal to 6.63x10-9Js.

- Carry no charge (not charged) and are not deflected by a magnetic or electric field

Answer 2

hey mate here's ur answer

they can travel through empty space.

The speed of light is constant in space.

A wavelength of light is defined similarly to that of water waves---distance between crests or between troughs.

•they travel perpendicular to each other
