Explanation:
Radiation means ‘energy that is transported from one spot to another without the need of direct contact between the two locations’, Light in each carries a different amount of energy, this is what we call electromagnetic radiation or electromagnetic waves. Gamma rays are the most energetic, and radio is the least.
<em>In order from longest to shortes wavelenghts we have:</em>
- Radio waves: they are made by various types of transmitters, given off by stars, sparks, and lightning, they have the lowest frequencies (longest wavelenghts) in the electromagnetic spectrum and are used mainly for communications.
- Microwaves: they are extremely high-frequency radio waves (Their wavelength is usually a couple of centimeters) made by various types of transmitters.
- Infra-red waves: they are just below visible red light in the electromagnetic spectrum, they're given off by hot objects.
- Visible lights is the tiny part of the electromagnetic spectrum our eyes can detect.
- Ultra-Violet: this light is given off by the Sun in large quantities. We call it "UV" for short and can also be used to kill microbes.
- X-rays: they are very high-frequency waves that carry a lot of energy. They will pass through most substances, and this makes them useful in medicine and industry to see inside things.
- Gamma rays: they are given off by stars and by some radioactive substances. They are extremely high-frequency waves (the shortest wavelength) and carry a large amount of energy. They pass through most materials.
In the image, I annexed you can see the electromagnetic spectrum with the type of radiations from the shortest to the longest wavelengths.
I hope you find this information useful and interesting! Good luck!

Geography is such a broad and all-encompassing subject, there is no one definition that applies to it.
What is Geography?
The science of geography examines the Earth and the natural and human forces that have shaped it.
The study of places and the interactions between people and their environs is known as geography. Geographers study the Earth's surface's physical characteristics, as well as the distribution of human communities there.
Hence, the significance of the Geography is aforementioned.
