Thermal Radiation: Black Body, Stefan & Wien

If the temperature of a hot body is increased by $50\%$ , then the increase in the quantity of emitted heat radiation will be approximately

Show answer and solution

Answer: (d)

$E \propto T^4$ ; $\dfrac{E'}{E} = (1.5)^4 \approx 5.06$
Increase $\approx 406\% \approx 400\%$
So the answer is (d) 400%.
