Refraction on water
Refraction is the bending of a wave caused by a change in its speed as it moves from one medium to another. This occurs because of the slow speed of light in…

Phase array
Spinning radar In general, electromagnetic waves (radio waves) propagate in all directions. In this case, radio waves can be transmitted or received in any direction. However, as the distance increases, the strength…

Superposition and Interference
Superposition occurs when two or more waves pass through each other. When two or more waves superimpose, the amplitudes are added together. It creates constructive interference or destructive interference.
Newton Ring
The Newton ring The interference of two reflections causes Newton rings. We can observe the Newton Rings when light is reflected from a plano-convex lens of a long focal length placed in…
