Assertion : Light is produced in gases in the process of electric discharge through them at high pressure.
Reason : At high pressure electrons of gaseous atoms collide and reach excited state.

A

If both assertion and reason are ture and the reason is the correct explanation of the assertion.

B

If both assertion and reason are true but reason is not the correct explanation of the assertion.

C

If assertion is true but reason both are false.

D

If assertion is false but reason is true.

Text Solution

Verified by Experts

Light is produced in gases in the process of electric discharge at low pressure. When accelerated electrons collide with atoms of the gas, atoms get excited. The excited atoms return to their normal state and in this process light radiations are emitted.
