Read the event described below. Try to identify the 5 different waves that are present in the scenario: Imagine that your family has just returned home from a day at the beach. You had fun playing in the ocean waves under a hot sun. You put some cold pizza in the microwave for dinner, and you turn on the radio. Just then, the phone rings. It's your friend calling to ask about homework.

1. Ocean waves- This is a surface wave, a type of mechanical wave.

2. Hot Sun- This is an ultraviolet wave, a type of electromagnetic wave.

3. Microwave- This is a microwave, a type of electromagnetic wave.

4. Radio- This is a radio wave, a type of electromagnetic wave.

5. Phone- This is a sound wave, a type of mechanical wave.

Explanation:

A wave arises as a result of the movement of energy without the movement of matter. There are basically three classes of waves, namely,

1. Electromagnetic waves: These are waves that do not a medium for their propagation. They are caused when the magnetic and electric fields interact with each other. Microwaves, radio waves, x-rays, and ultraviolet rays are examples.

2. Mechanical waves: These are waves that are propagated through a medium. They do not move through a vacuum. Water waves, pressure waves, and sound waves are examples.

3. Matter-wave: These arise because of the nature of matter which makes it act as a wave.
