Refraction occurs when a wave bends as it crosses the boundary between different mediums (eg. air to glass). The wave bends because waves travel at different speeds in different mediums.
When a wave enters a more dense medium (eg. air to glass), the wave slows down, and bends towards the 'normal'.
When a wave enters a less dense medium (eg. glass to air), the wave speeds up, and bends away from the 'normal'.
* The normal is an imaginary line which is perpendicular to where the light is entering the new medium.
Refraction occurs when a wave changes speed as it moves from one medium to another, causing it to bend. This happens instantly at the boundary between the two mediums.
No, the frequency of a wave does not change when refraction occurs. Refraction only affects the speed and direction of the wave as it travels through different mediums, but the frequency remains constant.
Reflection occurs when light bounces off a surface, changing direction but not entering the material. Refraction happens when light passes through a material and changes speed, causing it to bend.
The direction of light can be changed through reflection, refraction, or diffraction. Reflection occurs when light bounces off a surface, changing its direction. Refraction happens when light passes through a medium with a different optical density, causing it to bend. Diffraction occurs when light encounters an obstacle or aperture, causing it to spread out and change direction.
It is Refraction
This means no refraction occurs i.e. Total internal reflection (all light reflected) occurs

The angle if refraction also increases.
The direction of light can be changed through reflection, refraction, or diffraction. Reflection occurs when light bounces off a surface, changing its direction. Refraction happens when light passes through a medium with a different optical density, causing it to bend. Diffraction occurs when light encounters an obstacle or aperture, causing it to spread out and change direction.
That depends on the substances where the refraction occurs. The relationship between the angles, and the index of refraction of both materials, is given by Snell's Law.
When light travels at right angles into a transparent object (i.e. angle of incidence is zero), no refraction occurs.
It is Refraction
in concave and convex mirrors refraction happens
When a light ray moves from one substance to another, it can undergo refraction, reflection, or absorption. Refraction occurs when the light ray changes speed and direction as it enters a new medium. Reflection happens when the light ray bounces off the surface between the two substances. Absorption occurs when the light ray is absorbed by the new medium.
It is called refraction. Refraction occurs when a wave changes speed and direction as it travels from one medium to another, due to the change in its wave velocity and the change in the medium's optical density.
