Reflection, Refraction, Diffraction

REFLECTION, warp, DIFFRACTION

Reflection roves bounce off a surface
Refraction waves curved shape when they scarper though a boundary
Diffraction waves spread out ( winding) when they pass through a small opening or black market around a barrier


REFLECTION
-when a wave encounters a barrier, it squirt reflect the bounce off the obstacle
-i.e. light = mirror; strait = echo
-most objects we see reflect light rather than verbalise their own light
-Fermats principle = light travels in cracking lines and will take the path of least time

Laws of Reflection
1. The angle of relative incidence equals the angle of reflection (true for both flat and curve mirrors)
2. The incidence ray, reflected ray, and the normal all lie in the same plane.

Diffuse Reflection
-in diffuse, waves atomic number 18 reflected in many disparate ways form a rough surface
-in specular, waves are reflected in the same direction from a smooth surface


digression (light)
-when one medium ends and an different begins, that is called boundary
-when a wave encounters a boundary that is denser, part of it is reflected and a part of it is transmitted
-the frequency of the wave is not altered when crossing the boundary / barrier only when the speed and wavelength are
-the change in speed and wavelength smoke pull in the wave to bend if it hits the boundary at an angle other than 90 degrees
-this bending as light enters the water can cause objects under water to appear at a different location than they actually are

REFRACTION ( expert)
-sound waves bend when passing into cooler / warmer air because the speed of sound depends in the temperature of the air
-sound travels slower in cooler air

REFRACTION (water)
-water waves bend when they pass from deep water into shallow water, the wavelength shortens and they slow down.


DIFFRACTION
- involves a change in direction of waves as they pass through an opening or around a barrier in their pathIf you want to get a in force(p) essay, order it on our website: Ordercustompaper.com
