$diffraction vs refraction$

$diffraction vs refraction$

The size of the aperture (or object) determines the extent of diffraction, with the most significant diffraction occurring when the aperture is of the same order of magnitude as the wavelength of the wave. Diffractionĭiffraction is the spreading out of a wave when it passes through an aperture (gap/hole) or around an object. IMPORTANT NOTE: If a wave enters a medium at 90º to the surface (parallel to the normal) it is not refracted. The angle of refraction is greater than the angle of incidence.The angle of refraction is less than the angle of incidence.The angle of refraction is larger or smaller than the angle of incidence depending on how the speed changes: So if the particular phenomenon depends on the wavelength, then that would affect how the radio waves would behave. Radio waves have longer wavelengths (lower frequencies) than light. As a result, they would obey the same behaviour. There are generally two types of reflections-ġ.Refraction occurs because waves travel at different speeds in different mediums and this change in speed is caused by differences in density between the mediums. As with light, radio waves are electromagnetic waves. Refraction is the phenomenon which sends back the light in the different medium.Īccording to law of reflection, the angle of incidence is equal to angle of reflection.Īccording to law of refraction of light, the ratio of sine of angle of incidence and sine of angle of refraction is constant Reflection is the phenomenon which sends back the light in the same medium.

The phenomenon of reflection generally occurs in Lenses. The phenomenon of reflection generally occurs in a mirror. It is defined as the bending of waves around the corners of an. Refraction is the bending of light when it travels from one medium to another. Diffraction refers to various phenomena that occur when a wave encounters an obstacle or opening. Reflection is the bouncing back of light when it strikes the smooth surface. The ray generally bends towards the normal ray while travelling to rarer medium to a denser medium and it bends away from normal ray while travelling to denser to rarer medium.įigure 1: Diagram demonstrating Reflection and Refraction.ĭifferences between Reflection and Refraction: Diffraction is the bending of light at the corner of the hurdle when the light ray passes through the slit giving geometrical shadow. Refraction – Refraction is the process in which, when the incidence ray strikes the surface in some medium and it gets diverted or bent while passing through another medium. The angle in between the incident ray and the normal ray is called angle of incidence and the angle between the normal ray and reflected ray is called the angle of reflection. The ray which reflects back from smooth surface is called reflected ray.

In reflection, the ray which strikes the smooth surface is called the incident ray. Reflection – Reflection is the phenomenon in which light reflects back after striking a smooth surface. In the following paragraphs, we ll be trying to share in detail on both refraction and reflection as well as difference between the two. But, actually, there is an enormous difference between the two. When an electromagnetic wave is obliquely incident on the interface between two homogeneous media with different refractive indices, the requirement of phase.

Whenever anyone hears of the terms reflection and refraction, one is confused as both the terms sounds almost similar.
