Hint :In the spectrum of electromagnetic waves, the electromagnetic spectrum is a range of frequencies, wavelengths, and photon energies ranging from below 1 hertz to over $ {{10}^{25}} $ Hz, equivalent to wavelengths ranging from a few kilometres to a fraction of the size of an atomic nucleus. In general, electromagnetic waves in a vacuum tend to move at rates close to those of light. They do so, however, at a variety of wavelengths, frequencies, and photon intensities.

Complete Step By Step Answer:
Electromagnetic waves are used in our daily lives in the following ways:
Radio: A radio is a device that receives radio waves that are broadcast by radio stations. In space, radio waves can be produced by gases and stars. The majority of radio waves are utilised for TV and mobile communication.
Microwave: Microwaves emit this sort of radiation, which aids in home/office cooking. Astronomers use it to figure out and comprehend the structure of neighbouring galaxies and stars.
Infrared is a kind of light that is commonly used in night vision goggles. These gadgets are capable of reading and capturing the infrared light generated by our skin and hot objects. Infrared light is used to trace interstellar dust in space.
X-ray: X-rays are useful in a variety of situations. An x-ray machine, for example, can be used by a doctor to obtain an image of our bone or teeth. It is used by airport security officers to inspect and check baggage. In the cosmos, heated gases emit X-rays as well.
Gamma-ray offers a wide range of applications in medicine. Gamma-ray imaging is a technique for looking inside our bodies. Surprisingly, the universe is the world's largest gamma-ray producer.
Ultraviolet radiation is mostly emitted by the sun. It tans the skin and produces burns. UV radiation is emitted by hot materials in space.
Visible light is light that can be seen with the naked eye. Visible light is produced by light bulbs, stars, and other objects.

Note :
The electromagnetic spectrum is the total distribution of electromagnetic radiation by frequency or wavelength. While all electromagnetic waves travel at the speed of light in a vacuum, they do so over a wide range of frequencies, wavelengths, and photon energies.
Astronomers may use these data to determine physical attributes of objects like temperature, composition, and velocity. The electromagnetic spectrum encompasses a lot more than visible light. It protects against radiation wavelengths that are invisible to the naked eye.
