Electromagnetic Spectrum

Electromagnetic Spectrum

1. Doppler Effect

   • Wave length INCREASES and Frequency DECREASES as objects moves AWAY.
   • Wave length DECREASES and Frequency INCREASES as objects move TOWARDS.
   • A theory about the big bang.

2. CMBR

   • Cosmic Microwave Background Radiation

3. Waves

   • 1. Radiation
   • 2. Microwaves
   • 3. Infrared
   • 4. Visible Light
   • 5. Ultraviolet
   • 6. X-rays
   • 7. Gamma Rays
   • Uses: radio- TV microwaves- Heating Foods Infrared- Remote Control, Night vision goggles Visible Light- so we can see Ultraviolet- Sun beds, Night clubs X-rays- see in the body Gamma- Kill cancer, sterilise

4. Refracted.

   • Comes out at different angles- bends

5. Defracted.

   • When the light comes out at a rippe affect

6. Equation.

   • WaveSpeed=Frequency x Wavelength
     • (M/s)= (Hz) x (M)
