Light is a type of electromagnetic radiation that can be detected by the eye. It travels as a transverse wave. Unlike a sound waves, light waves do not need a medium to pass through,...
Light is called an 'electromagnetic wave' for historical reasons* in the following sense: It turned out that the effects of visible light and other radiation can be calculated using Maxwell's equations, which are also used to model the behaviour of electrically charged particles. This was an instant of a successful unification and it hasn't ...

These different colours of light have different wavelengths and frequencies. Red light has the longest wavelength, and the lowest frequency of the visible spectrum. Violet has the shortest wavelength, and the highest frequency of the visible spectrum.
Mixing coloured materials, such as paint, is an example of subtractive colour mixing. Red paint appears red to us because when white light strikes it, the red pigments reflect the red wavelengths of light and absorball of the wavelengths. This reflected light is what is seen by our eyes. The same is true for all of the other colours. So what about ...
Light travels very fast - at the speed of light in fact!Light travels as waves.Light travels in straight lines.May 24, 2024 · We know that light is a wave based on how it behaves – it exhibits the same properties of other waves we have examined – it interferes with itself, it follows an inverse-square law for intensity (brightness), and so on.
Jan 30, 2023 · Light waves are electromagnetic waves that are visible to the eye and can travel through a vacuum. Sound waves are mechanical waves, invisible to the human eye, and unable to travel in a vacuum. Read on for more information on the difference and properties of light and sound waves.
Nov 14, 2024 · Light is electromagnetic radiation that can be detected by the human eye. Electromagnetic radiation occurs over an extremely wide range of wavelengths, from gamma rays with wavelengths less than about 1 × 10 −11 metres to radio waves measured in metres.

Feb 3, 2024 · What is the main difference between light and sound? – Sound is only a wave, whereas light exhibits both wave and particle properties. – Sound is a longitudinal wave, but light is a transverse wave. – Sound needs a material medium to travel, light can propagate through vacuum also. – Light travels much faster than the sound.
