Question

Drag and drop the word or phrases to place the electromagnetic waves in order, from highest to lowest frequency.

Electromagnetic Wave Frequencies
Highest -

X-rays

Visible light waves
Infrared waves

Lowest - Radio waves

gamma rays
white light waves
ultraviolet waves
microwaves
nanowaves
nuclear waves

Answer 1

Order from highest frequency (shortest wavelength) to lowest frequency (longest wavelength):

1. gamma rays
2. X-rays
3. ultraviolet waves
4. visible light waves (white light waves)
5. infrared waves
6. microwaves
7. radio waves

Notes:
- "white light waves" = visible light, so it's placed with visible light.
- "nanowaves" is not a standard EM-band name; if it means waves with nanometer wavelengths, those lie in the ultraviolet–visible range (around items 3–4).
- "nuclear waves" is not a standard EM category; sometimes people use it informally to refer to gamma radiation from nuclear processes, which would place it with gamma rays.
