Answer:
Thermal radiations are electromagnetic waves having wavelength range from \[1\mu m\] to \[100\mu m\]. When they are absorbed by a body, they produce heat. Light radiations are electromagnetic waves having wavelength range from 4000 \[\overset{\text{o}}{\mathop{\text{A}}}\,\] to 7500\[\overset{\text{o}}{\mathop{\text{A}}}\,\]. They produce sensation of vision.
