Wave Reflection Definition
Wave reflection occurs when waves hit matter and bounce off. For example, sound waves create echoes by reflecting off surfaces.

Wave Reflection, Absorption & Transmittance
Fun Facts
- When a wave is reflected, it is sent off in a new direction.
- Light reflects off mirrors at equal angles of incidence and reflection.
- Waves are reflected when the density of matter is too high for the wave to pass through or be absorbed.
Why Do We Need To Know About Wave Reflection
Learning about how waves of sound and light bounce off things or get soaked up helps us understand how they work with different materials. This is really important for making things better in many jobs. For example, music studios use special foam to soak up sound so there’s no echo, making the music sound clearer. This shows how knowing about waves helps make better sound for music.
In the same way, how light waves bounce off or get soaked up is key for things like solar panels that turn light into electricity, and for plants making their food in photosynthesis when leaves reflect green light. These examples show us how waves are important in making clean energy, new technologies, and even in how nature works.
Frequently Asked Questions

In this lesson, we learn that:
- All waves have properties like amplitude, wavelength and frequency.
- Sound waves need matter to travel through. Light waves can travel through empty space.
- Waves interacting with matter can be reflected, absorbed, transmitted and refracted.
