Reflection of light and types of rays

Reflection

• The bouncing back of light from a shiny and smooth surface

• The bouncing back of light from any surface

• The bouncing back of light from a virus-free surface

Incident ray

• Ray which falls on the shiny smooth surface from the object

• Ray which is inclined towards the mirror.

• Ray which falls on mirror by mistake

Reflected ray

• Ray bounces back from a shiny smooth surface

• Ray which is supposed to be the incident ray

• Ray falls on the mirror from t a different angles

Normal

• L 90° or perpendicular is referred as normal

• Ray which is not specified

• A special ray

Angle of incidence

• Angle between normal and incident ray

• Angle between mirror and incident ray

• Total angle

Angle of reflection

• Angle between the reflected ray and normal

• Total angle

• No such angle is there

Angle of incidence (I) =Angle of reflection (r)

• True

• False
