The difference between sound and light They’re both waves, after all.

Physics. PHS 5041 Optics Refraction of Light Refraction always occurs simultaneously with some partial reflection Change in direction is with respect.

Refraction occurs at a boundary The speed of light must change at the boundary The angle of the light ray is measured from the normal, as was the case.

REFRACTION. When light travels from one material to another it usually changes direction The bending of light that occurs at the borderline of two materials.

REFRACTION (Bending of Light) Light slows down or speeds up when it enters and leaves another material.

Refraction and Snell’s Law Refraction: bending of light at the interface of 2 different materials.

In a vacuum (void of molecules), light travels at 3.0 x 10 8 m/s, Light travels at different speeds in different materials or mediums. while in water.

Refraction. Refraction is the bending (change in direction) of light when it travels from one medium into another. Caused by a change in speed Refraction.

Refraction. Light can bend not only when it reaches a reflective surface but also when it goes from one medium to another Medium (pl. media) –The substance.

When light travels from one material to another it usually changes direction The bending of light that occurs at the borderline of two materials is called.

Refraction of Light Optical density a property of a transparent material that is an inverse measure of the speed of light through a material Optical refraction.

Today’s Agenda Refraction notes Final Review

Refraction Refraction: The change in direction of a wave as it passes the boundary of two different mediums where the wave changes speed

Light in Different Mediums Light changes speed when it travels through a different medium Light traveling from a less to more optically dense medium it slows down - Light bends toward the normal Light traveling from a more to less optically dense medium it speeds up - Light bends away from the normal

Optical Densities Vacuum of Space Air Ice Water Glass Diamond Less More

Refraction of Light

Properties of Plane or Flat Mirrors As objects (or you) move away from the mirror Have the same amount of reflection Less detail, because the object appears further away.
