Answer:
Imagine you have an orange. This is your imaginary Earth. When you look at it in any direction, you won’t be able to see all sides of it. But when you peel the orange, flatten and stretch it out, you can begin to see everything.
Similarly, a map projection is a method by which cartographers translate a sphere or globe into a two-dimensional representation. In other words, a map projection systematically renders a 3D ellipsoid (or spheroid) of Earth to a 2D map surface.

Answer:
Can behave both as a particle and wave
Explanation:
Electromagnetic wave has the electric and magnetic wave propagating/oscillating together. Electromagnetic waves such as x Ray, gamma ray, radio waves are important in health care and modern information technology .
Electromagnetic waves have particles such as the electrons and protons. They are responsible for the existence of electromagnetic waves by the charged particles vibrating. Electromagnetic waves behave as waves majority of the time. Electromagnetic energy is released in distinct packs of energy called photons which are particles but acts like waves.
