A black body at 20 K is found to emit maximum energy at a wavelength 14 µm. When its temperature is raised to 1000K, then wavelength at which maximum energy emitted is

Wavelength is the distance between two consecutive crests or troughs of a wave. It is commonly used to describe electromagnetic waves like light, radio, and sound. Wavelength is inversely proportional to frequency, meaning longer wavelengths have lower frequencies and shorter ...

Rate of cooling at 600 K, if surrounding temperature is 300 K is R.

Temperature is a measure of the average kinetic energy of particles in a substance. It determines the direction of heat flow between objects with heat moving from higher to lower temperature. Temperature is measured in units such as Celsius, Kelvin ...
