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.

Explanation

To solve the problem, we will identify the parts of the electromagnetic spectrum corresponding to each wavelength and then arrange them in decreasing order of wavelength.

### Step-by-Step Solution:

1. **Identify the wavelength for muscular strain (λ₁)**:
- **Use**: Muscular strain treatment.
- **Part of the Spectrum**: Infrared radiation.
- **Reasoning**: Infrared waves are commonly used in physiotherapy to treat muscular strains due to their ability to penetrate the skin and provide heat.
