8 Physics Vocab 4

Refraction of light

Refraction Bending of light waves due to change in speed of light, when they travel from one medium to another
Refracted Ray The ray of light that bends after entering a different medium
Angle of refraction Angle between the refracted ray and the normal
Optically dense medium Speed of light is less in this medium and has greater refractive index
Lens a curved piece of transparent material, such as glass or plastic, that refracts light
Concave Lens This type of lens is thinner in the middle and thicker at edges
Convex Lens This type of lens is thicker in the middle and thinner at the edges
Concave lens image upright and smaller than the object
Concave lens effect on light This lens diverges light This lens refracts light rays that pass through it, away from the normal
Convex lens image image depends on how far the object is from focal length, can be big and small
Convex lens effect on light This lens converges light
Concave lens use flashlights, door viewers, correct nearsightedness
Convex lens use magnifying glass
Use of Combination of concave and convex lens telescopes, microscopes, camera
Refractive Index the ratio of the velocity of light in a vacuum to its velocity in a specified medium.
Optically rarer medium speed of light is more in this medium and has lower refractive index

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
