Diffraction occurs when waves encounter an obstacle or aperture and bend around it, spreading out in different directions. Reflection involves the bouncing back of waves off a surface at the same angle they hit it. Refraction is the bending of waves as they pass from one medium to another with different densities.
Refraction and Diffraction are two words that also relate to light. Refraction is the bending of light as it passes through different mediums, and diffraction is the bending of light as it passes around obstacles.
Light demonstrates wave characteristics when it undergoes phenomena such as interference, diffraction, and polarization. These behaviors are consistent with light behaving as a wave rather than a particle.
Actually it is refraction process and specifically indentified as total internal reflection. The condition for total reflection is that the ray has to traverse from denser medium to the rarer medium and the angle of incidence has to be more than the critical angle.
Reflection is used in headlights of cars to increase visibility, while in photography, it is used to control the amount of light entering the camera. Refraction is used in eyeglasses to correct vision, and in lenses of telescopes and microscopes to focus light for magnification. Overall, both reflection and refraction play crucial roles in various daily life applications involving light manipulation.
When light enters a glass block, it undergoes reflection and refraction. However at the glass air interface, refraction occurs to a larger extent than refraction and hence some of the light is reflected while the rest of it enters the glass block.
Refraction and Diffraction are two words that also relate to light. Refraction is the bending of light as it passes through different mediums, and diffraction is the bending of light as it passes around obstacles.
Reflection, refraction, and diffraction. Reflection is most common, when we see ourselves in the mirror. Refraction is evident when you insert a straw into a clear liquid (7-up, for example) and see the straw bend at the surface apparently. Diffraction is when light passes through a slit or opening, an interference pattern appears much wider than the slit on the other side.

In general waves can: Wrap around the obstacle. This happens when the wavelength is larger than obstacle size. Bounce back as an echo off the obstacle. This happens when the wavelength is shorter than the obstacle size. Be absorbed by the obstacle. This occurs when the natural frequency of the obstacle matches the frequency of the wave...so-called resonance. Pass through the obstacle. There are several ways this can happen. But visible light passing through a glass window is one example.
The hot black asphalt heats the air next to it and the hot air has a different index of refraction than cooler air just above it, the boundary between the two media with different indices of refraction creates a total internal reflection. Thus the appearance of (an inverted) object in the distance.
This means no refraction occurs i.e. Total internal reflection (all light reflected) occurs
Actually it is refraction process and specifically indentified as total internal reflection. The condition for total reflection is that the ray has to traverse from denser medium to the rarer medium and the angle of incidence has to be more than the critical angle.
Refraction and partial internal reflection occurs
The minimum index of refraction for total internal reflection at a 45-degree angle is 1.41. This means that the glass or plastic prism would need to have an index of refraction greater than or equal to 1.41 to achieve total internal reflection at that angle.

In addition to the primary image formed by one reflection off the back of the mirror, you may get images formed after two reflections and a total internal refraction: reflection off the back of mirror, refraction on inside of front surface of glass and reflection off back of the mirror. The refraction will only take place at a large angle.
We make that assumption from scanty, flimsy evidence. The only indication we have is that radio waves exhibit all the properties of reflection, refraction, diffraction, dispersion, polarization, and interference that are characteristic of waves, and that they all closely match the mathematics of wave motion. Other than that, there's nothing to go on.
