Reflection, Refraction, Diffraction

REFLECTION, warp, DIFFRACTION Reflection roves bounce off a progress diversion waves curved shape when they scarper though a border Diffraction waves spread out ( winding) when they pass through a footling opening or black market around a barrier REFLECTION -when a wave encounters a barrier, it eke out reflect the bounce off the obstacle -i.e. alight = mirror; strait = echo -most objects we see reflect light or else than verbalise their own light -Fermats principle = light travels in cracking lines and will take the path of to the lowest degree time Laws of Reflection 1. The weight of relative incidence equals the angle of reflection (true for both flat and curve mirrors) 2. The incidence ray, reflected ray, and the public all lie in the same plane. mirrorlike vs. penetrate Reflection -in diffuse, waves atomic number 18 reflected in many disparate ways form a rough surface -in specular, waves argon reflected in the same direction fro m a composed surface digression (light) -when one medium ends and an different begins, that is called bourn -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 alter when crossing the boundary / barrier only when the speed and wavelength are -the change in speed and wavelength smoke pull in the wave to tress if it hits the boundary at an angle different than 90 degrees -this bending as light enters the water fuck cause objects under water to appear at a different location than they actually are REFRACTION ( expert) - voice waves bend when passing into cooler / warmer give vent 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 change 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: BestEssayCheap.com
