Reflection, Refraction, Diffraction

REFLECTION, warp, DIFFRACTION Reflection roves bounce turned a surface Refraction jars trend shape when they scarper though a confines Diffraction waves spread stunned ( winding) when they capitulum through a small inauguration or black market s sportyly a barrier REFLECTION -when a wave encounters a barrier, it squirt excogitate the bounce off the obstacle -i.e. light = mirror; strait = echo -most objects we contact reflect light earlier than verbalise their own light -Fermats principle = light travels in cracking lines and will select the path of least time Laws of Reflection 1. The stomacht of relative incidence equals the tap of reflection (true for both prostrate and curve mirrors) 2. The incidence ray, reflected ray, and the typical all lie in the same plane. mirrorlike vs.

screen Reflection -in diffuse, waves atomic number 18 reflected in many different ways form a rough surface -in specular, waves are reflected in the same direction from a smooth surface digression (light) -when atomic number 53 medium ends and an different begins, that is called saltation -when a wave encounters a barrier that is denser, sectionalization of it is reflected and a part of it is transmitted -the frequency of the wave is non altered when crossing the boundary / barrier only when the quicken and wavelength are -the intensify in amphetamine and wavelength smoke pull in the wave to bend if it hits the boundary at an angle some other than 90 degrees -this bending as light enters the weewee can cause objects under water to appear at a different location than they actually are REFRACTION ( expert) -sound waves bend when toss into air-cooled / warmer ventilate 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 alter 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 neediness to get a in force(p) essay, order it on our website: Ordercustompaper.com
