Detailed explanation-1: -Reflection is where a wave strikes an object and bounces off. When a wave strikes a flat reflective surface it will reflect back at the same angle at which it struck the surface. This is called the Law of Reflection.
Detailed explanation-2: -Reflection. An echo is an example of wave reflection. Reflection occurs when waves bounce back from a surface they cannot pass through. Reflection can happen with any type of waves, not just sound waves. For example, light waves can also be reflected.
Detailed explanation-3: -Echoes. An echo is a sound that is repeated because the sound waves are reflected back. Sound waves can bounce off smooth, hard objects in the same way as a rubber ball bounces off the ground. Although the direction of the sound changes, the echo sounds the same as the original sound.
Detailed explanation-4: -Reflection. When water waves hit the side of a swimming pool, they bounce back. When an object or wave hits a surface through which it cannot pass, it bounces back. This is called reflection. To show reflection of a wave, draw a line in the direction of the motion of the wave.
Detailed explanation-5: -Electromagnetic waves, inducing light. Sound waves. Seismic waves. Ripples in water. Vibrations on a guitar string. 04-Oct-2021
