Which kind of electromagnetic radiation carries information to and from a cell phone
when it is used for a phone call?
Microwaves
X-rays
Infrared radiation
Ultraviolet radiation - answer>>>Microwaves
A cashier who has been handed a hundred-dollar bill may check its authenticity by holding
it under a special lamp that emits electromagnetic radiation mostly at wavelengths
slightly shorter than visible light. The electromagnetic radiation makes a pattern of
previously invisible markings on the bill glow brightly, or fluoresce.
Which kind of electromagnetic radiation does the lamp emit to produce this effect?
Microwaves
Infrared radiation
Ultraviolet radiation
X-rays - answer>>>Ultraviolet radiation
After natural disasters, first responders can locate survivors in the rubble by using thermal
detectors. Because the victims' bodies are warmer than their surroundings, the difference
in temperature is detected by electromagnetic waves.
