Study Notes
Light and Optics
- When light hits a surface and bounces off, it is called reflection.
Lenses
- A concave lens makes an object look smaller.
Communication Waves
- Cell phones use radio waves for communication.
Light Absorption
- The process of soaking up or taking in light without reflecting it back is called absorption.
Light Transmission
- An object that allows some but not all light to pass through is called a translucent object.
Morse Code
- In Morse code, signals can be transmitted using flashing lights.
Lens Effect
- A lens affects the light passing through it by refracting (bending) it.
