A slingshot is a Y-shaped stick with rubber bands between the
prongs for shooting stones and other small projectiles. A stone is
shot by first placing it in the slingshot holder, which is attached
to the rubber bands. The stone and holder are then pulled back,
stretching the rubber bands. When released, the stone is
propelled forward and leaves the slingshot at a high speed.
Which type of energy transformation occurs from the point when
the rubber bands are fully stretched to when the stone leaves the
slingshot?

Which kind of electromagnetic radiation carries information to
and from a cell phone when it is used for a phone call?
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?
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.
Which part of the electromagnetic spectrum is being detected?
