Answer to Question #219592 in Mechanical Engineering for Molahlegi

Question

What changes would you notice if the sun emitted radiation at an effective temperature of 2000 K instead of 5762 K?

Answer 1

Since the emitted radiation has a low temperature than the usual one, there will be a reduction in the energy of the radiation. Therefore, the frequency of the rays will reduce just as its intensity. One can feel a reduction in the temperature of the rays that is heating their body.

The temperature of the maximum heat that is heating the earth's surface will reduce indicating a reduction in the total heat radiating from the sun.
