Electro Magnetic Spectrum

Question 1

Radio waves

Answer 1

Longest wavelength, lowest frequency

Used to cook foods and for phone and radio transmission

Question 2

Infrared waves

Answer 2

Shorter wave length than radio waves but has a higher frequency than radio waves

You can only feel these types of waves

Used for finding ppl in the dark and for remote controls

Question 3

Visible light

Answer 3

Shorter wave lengths than infrared waves and a higher frequency than infrared waves.

Only waves we can see

Visible light waves go from red to violet because of their frequencies

Question 4

Ultraviolet light

Answer 4

Frequency and energy high enough to penetrate living cells.

We need this to get vitamin D

Shorter wavelengths than visible light and higher frequencies than visible light.

Used to sterilize tools in the hospital

Question 5

X-ray

Answer 5

Has enough energy to penetrate deep into the cell tissue but are stopped by dense materials

Shorter wavelengths than ultraviolet and higher frequency than ultraviolet

Used to look at cracks such as bones

Question 6

Gamma rays

Answer 6

Shortest wavelengths and highest frequency and carry the most energy.

Most damaging to cell tissue

Hard to stop

Released by at amici reaction like nuclear bombs.
