Question

Absorptive power of a body depends on which of the following?

• A. Temperature
• B. Wavelength
• C. Pressure
• D. All of the above

Answer 1

Answer: (A), (B)

The correct options are
A Temperature
B Wavelength

Absorptive power depends on the difference between the temperature of the surrounding and the body. Absorptive power is high if the surrounding is at a higher temperature than the body. Absorptive power also depends upon the wavelength of radiation incident on it. It is high for a particular wavelength and becomes less and lesser as we go towards wavelengths different from that wavelength.
