Study Notes
Law of Reflection
- States that the angle of incidence is equal to the angle of reflection.
- Both angles are measured from the normal, an imaginary line perpendicular to the surface.
Types of Reflection
- Specular reflection refers to mirror-like reflection, where light reflects at a definite angle, creating a clear image.
Reflection in Geophysics
- In geophysics, reflection is utilized to study seismic waves, helping to analyze the Earth's subsurface structure.
Grazing Incidence Reflection
- Electromagnetic waves, particularly X-rays, can be reflected at shallow angles using special mirrors known as grazing mirrors.
Effects of Reflection in Acoustics
- In acoustics, reflection causes echoes, where sound waves bounce off surfaces and return to the listener, affecting sound clarity and volume.
