   Resource. Refraction is the bending of light (it also happens with sound, water and other waves) as it passes from one transparent substance into another. This bending by refraction makes it possible for us to have lenses, magnifying glasses, prisms and rainbows. Even our eyes depend upon this bending of light.

   Refraction is the bending of the path of a light wave as it passes across the boundary separating two media. Refraction is caused by the change in speed experienced by a wave when it changes medium. In Lesson 1, we learned that if a light wave passes from a medium in which it travels slow (relatively speaking) into a medium in which it travels ...

   The speed of light is greater in medium 1 than in medium 2 in the situations shown here. (a) A ray of light moves closer to the perpendicular when it slows down. This is analogous to what happens when a lawn mower goes from a footpath to grass. (b) A ray of light moves away from the perpendicular when it speeds up.

   How does a light ray affect a glass block?

   • A light ray speeds up as it passes from glass into air, and bends away from the normal by the same angle. Slide 1 of 3, Light ray hits glass block at right angles to surface. Wave slows, its wavelength decreases as it enters glass. As wave returns to air, speed and wavelength increase to original values.,

   What happens when a light ray refracts away from a normal ray?

   • When light travels from a denser medium into air, it will refract away from the normal. As can be seen in the diagram the light ray changes direction as it enters and leaves the block. In all ray diagrams, all angles of incidence and refraction are measured between the ray and the normal.

   What happens when a light ray moves from one medium to another?

   • When a wave or light ray moves from one medium to another its speed changes. The direction of the ray may also change. This property of waves is called refraction and commonly occurs with light rays. is when you see the bottom of a swimming pool. The light travels from the bottom of the pool, through the water, then through the air into your eye.

   How do you refraction a ray through a glass block?

   • At a boundary, waves are reflected, refracted, or absorbed. Waves, such as ultrasound, can be used in medicine and other industries. To investigate the refraction of light through a glass block. Set up a ray box, slit and lens so that a narrow ray of light is produced. Place a 30 centimetre (cm) ruler near the middle of a piece of plain A3 paper.

   How does bending affect refraction?

   • The amount of bending depends on two things: Change in speed – if a substance causes the light to speed up or slow down more, it will refract (bend) more. Angle of the incident ray – if the light is entering the substance at a greater angle, the amount of refraction will also be more noticeable.

   How do you draw a refraction diagram?

   • Step 1: Draw a parallel ray on the left Step 2: Draw the refracted ray at the first surface Step 3: Draw the refracted ray at the second surface Practice drawing refraction diagrams as much as you can! It's very important to remember which way the light bends when it crosses a boundary: As the light enters the block it bends towards the normal line
