1.5) Absorption, reflection, refraction Flashcards
What three things can happen to the light once it hits a surface?
- It may be transmitted
- reflected
- absorbed
What do light waves travel as?
Electromagnetic waves
What is reflection?
Reflection is when light bounces off an object
What is the speed of light
300000 km/s (three hundred thousand)
Why does light refract when it enters a different medium?
The refraction caused by a change in speed
What is refraction?
Refraction is the bending of light
What is a convex lense?
A convex lens is a converging lens
What effect does convex lens have on light rays?
Convex lens causes the light rays to bend to a specific focal point
What is concave lens?
A concave lens is a diverging lens
What effect does a concave lens have on light rays?
Concave lens causes light rays from a specific focal point to be spread out
How do convex lenses change how you see things?
Objects will appear bigger
