Application +4 | -1

Two spheres of the same materials have radii

1m

and

4m

and temperatures

4000\,K

and

2000\,K

respectively. The ratio of the energy radiated to that by the second by the first sphere to that by the second is

View answer and explanation

Correct option: A

1:1

Option A (

1:1

) is correct because the ratio of energy radiated depends on the product of the area squared and temperature to the fourth power, which simplifies to 1:1 in this case.
