Question 23

time between the arrival of two consecutive crests or troughs

Answer 23

period

Question 24

shortest frequency, longest wavelength

length of a football field

Answer 24

radio waves

Question 25

radar

Answer 25

radio detection and ranging

Question 26

produce more energy due to shorter wavelengths and higher frequencies basically a high frequency radio wave and are made by various types of transmitter

Answer 26

microwaves

Question 27

higher temperature produce shorter infrared rays shorter wavelength and higher frequency than microwaves literally means below the "red" - lower frequency than the red part of the visible light

Answer 27

infrared ration

Question 28

shorter wavelength and higher frequency than infrared waves electromagnetic waves that we can see -- LIGHT

Answer 28

visible light

Question 29

above violet shorter wavelength and higher frequency than visible light carry more energy than visible light doesn't reach earth

Answer 29

ultraviolet rays

Question 30

shorter wavelength and higher frequency than UV rays carry a great amount of energy can penetrate most matter called "roentgen rays"

Answer 30

x-rays

Question 31

can penetrate soft substances like flesh and bones

Answer 31

soft x-ray

Question 32

more penetrating; used in industries

Answer 32

hard x-rays

Question 33

powerful among the seven because of the high frequency shorter wavelength and higher frequency than x-rays carry the greatest amount of energy and penetrate the most

Answer 33

gamma rays
