Class 12 Physics simulations · Electromagnetic Waves

Explore the EM spectrum

Slide across the spectrum: the source glows with that radiation and shows its wavelength and frequency.

Open the simulation

What to notice

Shorter wavelengths correspond to higher frequency and photon energy.

Key relation

f = c/λ; E = hf

Try this

Move from radio waves toward gamma rays, and stop in visible light to see its 7 colours.
