Transverse wave

- Mathematics and experiments show that light is a transverse wave – the electric and magnetic field vectors point in directions that are perpendicular to the direction of motion of the light wave (and as it turns out, they also rare always perpendicular to each other).
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.
Light, visible light, or visible radiation is electromagnetic radiation that can be perceived by the human eye. [1] Visible light spans the visible spectrum and is usually defined as having wavelengths in the range of 400–700 nanometres (nm), corresponding to frequencies of 750–420 terahertz.
Light may change direction when it encounters objects (such as a mirror) or in passing from one material to another (such as in passing from air to glass), but it then continues in a straight line or as a ray.
Is light a wave or a particle? How is it created? And why can’t humans see the whole spectrum of light? All your questions answered.
In all of these cases, light is modeled as traveling in straight lines called rays. Light may change direction when it encounters objects (such as a mirror) or in passing from one material to another (such as in passing from air to glass), but it then continues in a straight line or as a ray.
In Lesson 1, we will investigate the variety of behaviors, properties and characteristics of light that seem to support the wave model of light. On this page, we will focus on three specific behaviors - reflection, refraction and diffraction.

Why is light a transverse wave?
Light is a transverse wave, which means the direction of motion of the light wave is at right angles to these fluctuations in the intensity of the electric and magnetic fields. Polarization is the property of transverse waves which allows them to have their electric field components oscillating in a single direction.
