First, we will examine the wavelike properties of light. Visible light is one type of electromagnetic radiation, which is a form of energy that exhibits wavelike behavior as it moves through space. Other types of electromagnetic radiation include gamma rays, x-rays, ultraviolet light, infrared light, microwaves, and radio waves.
Dec 7, 2022 · Light has the properties of waves. Like ocean waves, light waves have crests and troughs. The distance between one crest and the next, which is the same as the distance between one trough and the next, is called the wavelength .
IIT JEE Study Material. Properties of Light. Light is a form of energy that causes the sensation of vision. Different theories on the nature of light were proposed on the basis of the fact that energy can be transferred from one point to another, either by particle motion or by wave motion.
Light has seven main properties. 1. Light is electromagnetic radiation that can be perceived by the eye. Other electromagnetic radiation, such as x-rays or infrared rays, are not detected by our eyes. Electromagnetic spectrum. source. 2.
Summary. Light and other forms of electromagnetic radiation move through a vacuum with a constant speed, c, of 2.998 × 10 8 m s −1. This radiation shows wavelike behavior, which can be characterized by a frequency, ν, and a wavelength, λ, such that c = λν. Light is an example of a travelling wave.
Key Points. The electromagnetic spectrum includes common regimes such as ultraviolet, visible, microwave, and radio waves. Electromagnetic waves are typically described by any of the following three physical properties: frequency (ν), wavelength (λ), or intensity (I).
