Wave Reflection

The bouncing back of a wave when it encounters a boundary or obstacle. Wave reflection is a fundamental phenomenon in physics and can be observed in various everyday situations, such as echoes and the reflection of light. It plays a crucial role in fields like acoustics and optics. When a wave reflects, it undergoes a change in direction and may also experience a change in amplitude or frequency. Understanding wave reflection is essential for studying wave behavior and designing technologies like mirrors and sonar systems.

Wave Refraction

Wave refraction is the bending of waves as they pass from one medium to another. It occurs due to a change in the wave's speed or direction. When waves enter a medium with a different density, they can change direction, causing them to bend. This phenomenon is commonly observed when waves pass from deep water to shallow water, resulting in a change in their speed and direction. Snell's Law is used to calculate the angle of refraction. Refraction plays a crucial role in various natural phenomena, such as the formation of rainbows and the behavior of light in lenses.

Wave Refraction

The bending of waves as they pass from one medium to another. Wave refraction occurs when waves change direction due to differences in wave speed caused by variations in water depth. This phenomenon is commonly observed at the beach, where waves bend as they approach the shore. It is an important process in coastal erosion and sediment transport.
