Question

what are the characteristics of light class 6​

Answer 1

Answer:

Five characteristics of light are:

Light consists of packets of energy called photons.

Light is the relatively narrow frequency band of electromagnetic waves.

Light travels at such a high speed, 3 × 10 8 m/sec.

Light behaves both as a wave and particle.

Light travels fast in a vacuum

Answer 2

Light is an energy form. Light is essential in our existence because without it, we would have to survive in the dark, going in circles with no beginning or finish.

Explanation:

• Light is a type of electromagnetic radiation that has both a wave and a particle character. It may be thought of as packets of energy called photons that have both a wave and a particle nature. As a result, we refer to light as having a dual nature.
• As light travels from one material to another with varying optical density, its speed changes. In optically denser materials with great refractive indices, the speed of light is the slowest.
• Reflection, refraction, interference polarisation, and other phenomena occur in light. All of these occurrences can be explained either by the wave character of light or by the particle nature of light.
• When we talk about light, we're referring to the electromagnetic spectrum's visible light. The wavelength of visible light varies between 400 and 800 nanometers.
