Frequently asked questions
What is Waves?
Waves covers Waves in air, fluids and solids and Electromagnetic waves in GCSE AQA Higher Combined Science Physics. 13 lessons in 2 subtopics.
What is the difference between transverse and longitudinal waves?
In a transverse wave, particles vibrate perpendicular (at right angles) to the direction of energy transfer, as in water ripples. The Transverse vs. Longitudinal Waves notes cover this in full.
What are examples of transverse waves?
Examples of transverse waves include ripples on a water surface, light waves and a wave on a rope flicked up and down. The Transverse vs. Longitudinal Waves notes cover this in full.
What is refraction of electromagnetic waves?
Refraction is the bending of electromagnetic waves when they pass from one medium to another, due to a change in wave speed. The EM Wave Interactions with Matter notes cover this in full.
What is the wave equation?
The wave equation is v = fλ: wave speed (m/s) = frequency (Hz) × wavelength (m). The Wave Equation & Changing Mediums notes cover this in full.
What is the wavelength range of visible light?
Visible light ranges from red, with a wavelength of about 700 nanometres, to violet, with a wavelength of about 400 nanometres. The The Electromagnetic Spectrum notes cover this in full.
What is the amplitude of a wave?
The amplitude of a wave is the maximum displacement of a point on the wave away from its undisturbed position. The Wave Characteristics: Amplitude, Wavelength & Frequency notes cover this in full.
What are gamma rays used for?
Gamma rays are used in medical gamma cameras to image internal organs, using isotopes such as technetium-99m, and in industry to sterilise medical equipment and food products. The Producing and Absorbing Radio Waves and Gamma Rays notes cover this in full.
What is wavelength?
Wavelength is the distance from a point on one wave to the equivalent point on the adjacent wave. The Wave Characteristics: Amplitude, Wavelength & Frequency notes cover this in full.
