Electromagnetic Radiation

Question 1

Visible light

Answer 1

a very small portion of the EM spectrum, including all of the wavelengths of light that the average unaided human eye can detect

Question 2

Radio waves

Answer 2

waves with the longest wavelength, the lowest frequencies, and lowest energies of all types of EM radiation

Question 3

Microwaves

Answer 3

waves with higher frequencies and energies than radio waves but lower than those of infrared radiation

Question 4

Infrared (IR)

Answer 4

waves with higher frequencies than those of microwaves but lower than those of visible light

Question 5

Ultraviolet (UV)

Answer 5

waves with wavelengths that are just shorter than those of visible violet light but longer than those of X-rays; UV wavelengths are comparable to the size of molecules

Question 6

X-rays

Answer 6

waves with wavelengths that are shorter than UV rays but longer than gamma rays; X-rays have higher frequencies and higher energies than ultraviolet radiation

Question 7

Gamma rays

Answer 7

waves with the shortest wavelengths and the highest frequencies and energies of all EM radiation
