The Electromagnetic Spectrum | GCSE Physics Questions
The EM spectrum is a continuous range of transverse waves that travel at the speed of light in a vacuum.
Which EM wave has the highest frequency?
What is The Electromagnetic Spectrum | Questions?
"The range of all types of EM radiation, organised by frequency and wavelength."
Which EM wave has the highest frequency and is the most dangerous?
Exposure to which of these EM waves can cause skin cancer and premature aging?
Arrange these EM waves in order of INCREASING energy: Radio, Visible, UV, Gamma.
EM Spectrum Order
Radio, Micro, Infrared, Visible, UV, X-ray, Gamma.
Order of increasing frequency and decreasing wavelength.
All travel at 300 million m/s in a vacuum.
Higher frequency waves transfer more energy and are more ionising.
Mnemonic: "Raw Meat Is Very Unhealthy, X-ray Gamma" (or create your own to remember the order!).
