A body with surface area (A), temperature (T) and emissivity (e) = 0.6 is kept inside a spherical black body. What will be the maximum energy radiated ?
[`sigma` is Stefan's constant]

A

`0.2sigmaAT^(4)`

B

`0.4sigmaAT^(4)`

C

`0.6sigmaAT^(4)`

D

`0.8sigmaAT^(4)`

Text Solution

Verified by Experts

The correct Answer is:
C
According to Stefan's law for a body, the maximum enregy radiated by a body,
`E=esigmaAT^(4)=0.6[sigmaAT^(4)]`

A spherical body of area A and emissivity e=0.6 is kept inside a perfectly black body. Total heat radiated by the body at temperature T

A hot body will radiate maximum energy if its surface is

The temperature at which a black body ceases to radiate energy is .

A spherical body of emissivity e, placed inside a perfectly black body (emissivity = 1) is maintained at absolute temperature T. The energy radiated by a unit area of the body per second will be ( sigma is Stefan's constant)

The total radiant energy per unit area, normal to the direction of incidence, received at a distance R from the centre of a star of radius r whose outer surface radiates as a black body at a temperature T K is given by (where sigma is Stefan's constant)

Assuming the Sun to be a spherical body of radius R at a temperature of TK, evalute the total radiant powerd incident of Earth at a distance r from the sun where r_0 is the radius of the Earth and sigma is Stefan's constant.

Assuming the sun to have a spherical outer surface of radius r radiating like a black body at temperature t^(@)C . The power received by a unit surface (normal to the incident rays) at a distance R from the centre of the sun is where sigma is the Stefan's constant.
