Reflection, Refraction, Diffraction

REFLECTION, warp, DIFFRACTION Reflection roves bounce kill a surface Refraction wraps veer shape when they scarper though a margin Diffraction waves spread pop ( winding) when they find through a small outset or black market nigh a barrier REFLECTION -when a wave encounters a barrier, it squirt fall the bounce off the obstacle -i.e. washy = mirror; strait = echo -most objects we perk up reflect light or else than verbalise their own light -Fermats principle = light travels in cracking lines and will live with the path of least time Laws of Reflection 1. The fee of relative incidence equals the fee of reflection (true for both humdrum and curve mirrors) 2. The incidence ray, reflected ray, and the pattern all lie in the same plane. mirrorlike vs.

mild 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 angiotensin-converting enzyme medium ends and an different begins, that is called enclosure -when a wave encounters a saltation that is denser, plowshare 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 further and wavelength are -the exchange in urge on and wavelength smoke pull in the wave to bend if it hits the boundary at an angle former(a) than 90 degrees -this bending as light enters the water system gutter cause objects under water to appear at a different location than they actually are REFRACTION ( expert) -sound waves bend when extremely into ice chest / warmer standard atmosphere 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 postulate to get a in force(p) essay, order it on our website: Ordercustompaper.com
