Question

.
Light
reflection
and refraction,​

Answer 1

Answer:

Reflection and refraction. Light rays change direction when they reflect off a surface, move from one transparent medium into another, or travel through a medium whose composition is continuously changing. ... The reflected ray is always in the plane defined by the incident ray and the normal to the surface.

Answer 2

Answer:

LIGHT:

⭐ Light is a form of electromagnetic radiation with a wavelength which can be detected by the human eye. It is a small part of the electromagnetic spectrum and radiation given off by stars like the sun.Light exists in tiny energy packets called photons. Each wave has a wavelength or frequency.

REFLECTION:

⭐ When light bounces back after striking a surface, we say the light has reflected. This is known as reflection of light.

REFRACTION:

⭐ Refraction is the bending of a wave when it enters a medium where its speed is different. The refraction of light when it passes from a fast medium to a slow medium bends the light ray toward the normal to the boundary between the two media.
