The diagram shows changing wavelengths along the electromagnetic spectrum.

A horizontal spring showing wavelengths from very long to very short. The very long is labeled Y and the very short are labeled Z.
Which labels belong in the areas marked Y and Z?

Y: Ultraviolet
Z: Radio
Y: Gamma rays
Z: Visible light
Y: X-rays
Z: Infrared
Y: Radio
Z: Gamma rays

In the electromagnetic spectrum, the wavelengths range from very long to very short. The correct labels for areas marked Y (very long wavelengths) and Z (very short wavelengths) would be:

  • Y (very long wavelengths): Radio
  • Z (very short wavelengths): Gamma rays

So, the answer is: Y: Radio Z: Gamma rays.
