Microwaves, X-rays, UV-rays and infrared rays-which of the above electromagnetic waves has
(i) the shortest wavelength?
(ii) the lowest frequency?

Explanation

To solve the question regarding which electromagnetic waves have the shortest wavelength and the lowest frequency among microwaves, X-rays, UV rays, and infrared rays, we can follow these steps:

### Step 1: Understand the Electromagnetic Spectrum
The electromagnetic spectrum is a range of all the different frequencies of electromagnetic radiation. It includes radio waves, microwaves, infrared rays, visible light, ultraviolet rays, X-rays, and gamma rays. The spectrum is arranged such that as we move from left to right, the wavelength decreases and the frequency increases.

### Step 2: Identify the Position of Each Type of Wave
- **Microwaves**: Located between radio waves and infrared rays.
- **Infrared Rays**: Located just after microwaves.
