The Electromagnetic Spectrum — Interactive Lesson (Ages 14–16)

Radio, microwaves, the TV remote, sunlight and X-rays are all the same kind of wave. This 21-slide interactive lesson on electromagnetic spectrum takes pupils from first ideas to exam-style explanations, with 13 self-marking activities and nothing to prepare beforehand.

Teaching The Electromagnetic Spectrum in GCSE Physics

Pupils put the electromagnetic waves in order of wavelength and frequency, learn that all travel at 3 × 10⁸ m/s in a vacuum and use v = f × λ to calculate wavelengths. They match radio waves, microwaves, infrared, visible light, ultraviolet, X-rays and gamma rays to their uses, and explain the dangers of ultraviolet and ionising radiation.

What Pupils Will Learn

• List the electromagnetic waves in order of wavelength and frequency.
• State that all electromagnetic waves travel at the same speed in a vacuum.
• Use the wave equation v = f × λ.
• Describe uses of each type of electromagnetic wave.
• Describe the dangers of ultraviolet, X-rays and gamma rays.
