Electromagnetic wave with wavelength (i) `lambda_1` are used to treat muscular strain (ii) `lambda_2` are used by a FM radio station for broadcasting. (iii) `lambda_3` are used to detect fracture in bones (iv) `lambda_4` are absorbed by the ozone layer of the atmosphere. Identify and name the part of elctromagnetic spectrum to which thest radiations belongs. Arrange these wavelengths in decreasing order of magnitude. |

Answer» (i) `lambda_1` belongs to Infrared radiations (ii) `lambda_2` belongs to VHF radiations (iii) `lambda_3` belongs to X-rays (iv) `lambda_4` belongs to ultraviolet rays. The arrangement of wavelengths in decreasing order of magnitude are `lambda_2gtlambda_1gtlambda_4gtlambda_3`. |
