Reaction which involve release of heat are called exothermic reactions. All combination reactions are considered to be exothermic in nature. Eg :- C (s) + O2 (g) ----> CO2 (g) + Δ. Reactions which involve absorption of heat are called endothermic reactions. All decomposition reactions are considered to be endothermic in nature. Eg :- NaHCO3 (s) --Δ--> Na2CO3 (aq) + H2O (l) + CO2 (g).

What is the difference between Refraction and Reflection of Light? Class 10 Science Chapter Light.

Posted by Jasleen Gill 4 years, 6 months ago (8726093)

CBSE > Class 10 > Science

2 answers

Sia ? 4 years, 6 months ago (6945213)

Reflection	Refraction
This phenomenon usually occurs in mirrors.	This phenomenon usually occurs in Lenses.
Reflection can simply be defined as the reflection of light when it strikes the medium on a plane.	Refraction can be defined as the process of the shift of light when it passes through a medium leading to the bending of light.
The light entering the medium returns to the same direction.	The light entering the medium travels from one medium to another.
Considering the light waves, they bounce from the plane and change direction.	The light waves pass through the surface while simultaneously change from medium to medium.
The angle of incidence of the light is equal to the angle of reflection.	The angle of incidence is not equal to the angle of reflection.

Adithya Dev A 4 years, 8 months ago (10643926)

REFLECTION = phenomenon of bouncing back of light to the same medium after striking a surface. Occurs in the case of MIRRORS. No dependence on optical density of a medium. REFRACTION = phenomenon of bending of light rays as they move obliquely from one medium to another with different optical densities. Occurs in the case of lenses. Depends on optical density of the pair of media.

The elder brother tells him that that grade gap can be erased but the five years age gap cannot be.
