Explanation:
Statement 1: Transfer of heat by radiation requires a medium
- This statement is incorrect. Radiation is the transfer of heat through electromagnetic waves and does not require a medium for propagation. Unlike conduction and convection, radiation can occur in a vacuum because it does not rely on the movement of particles to transfer heat. Therefore, heat transfer by radiation does not need a medium.
Statement 2: All hot bodies radiate infrared radiation
- This statement is correct. According to Planck's law of black-body radiation, all objects above absolute zero temperature emit electromagnetic radiation, with the intensity and wavelength distribution depending on the temperature of the object. Hotter objects emit shorter-wavelength radiation, including visible light and ultraviolet rays, but all objects also emit infrared radiation as a form of heat transfer. Therefore, all hot bodies radiate infrared radiation along with other wavelengths of electromagnetic radiation.
Therefore, the correct answer is Option B: 2 only.
