What isreflection

By reflection of light, concave mirrors give real, inverted images if the object is beyond the focus and a virtual, erect, enlarged image if the object has a distance less than the focal length from the pole of the mirror.

The key difference is that unpolarized light has vibrations in multiple planes, whereas polarized light has vibrations in only one plane.

Total internalreflection

Sequences of light pulses are used to transmit information through an optical fibre network with the help of this total internal reflection. Medical instruments like ‘endoscopes’ use the total internal reflection of light through an optical fibre bundle to image internal organs.

In the case of curved mirrors with a smooth surface, we can see the images of reflection either virtually or really. That is, the images produced by curved mirrors can be either real (collected on a screen and seen), or virtual (cannot be collected on a screen, but only seen).

By the reflection of light convex Mirrors always give a virtual, erect, diminished image of the object kept infront of the mirror.

Choose the correct answer: What is the case of reflection, in the course of the second medium being a perfect dielectric?

The phenomenon, total internal reflection, is taken advantage of fibre in piping light in a curved path. The light directed down a narrow fibre of glass or plastic repeatedly reflects from the fibre-air interface at an angle larger than the critical angle. Optical fibres can transmit light over long distances without any loss of intensity.

Since the angle of incidence is measured between the incident ray and the normal, so, here the angle of incidence is not  60°

Refraction oflight

The angle of incidence and the angle of reflection are calculated by drawing a normal line that is perpendicular to the reflecting surface.

Unlike mirrors, most natural surfaces are rough on the scale of the wavelength of light, and, as a consequence, parallel incident light rays are reflected in many different directions irregularly, or diffusely. Hence, diffuse reflection helps in seeing the objects and is responsible for the ability to see most illuminated surfaces from any position.

Find angle α made by the system of the two mirrors shown in the figure above so that the incident ray at A and the reflected ray at B are parallel.

Diffused light is a more flattering light for portraits as it does not direct attention to any one part of the subject.

The given statement is true. For complete wave reflection, the angle of incidence should be the same as the angle of the reflection. In such cases, the reflection coefficient is unity and the transmission coefficient is zero.

The plane mirrors with a smooth surface produce this type of reflection. In this case, the image is clear and very much visible. The images produced by plane mirrors are always virtual, that is they cannot be collected on a screen.

We know that light is a form of energy which can undergo various phenomena like refraction, reflection, diffraction, and interference. In this session, let us know more about the laws of reflection (first law of reflection and second law of reflection), types of reflection, examples, differences, and total internal reflection.

For the incident ray at A and the reflected ray at B to be parallel, angles i + r and i’ + r’ have to be supplementary. (geometry: parallel lines cut by a transversal).

We first complete the given diagram with the angles of incidence and reflection as shown above and also label the incident and reflected rays.

Reflection, refraction diffraction

Choose the correct option: What is the dimension of the object as compared to the wavelength of the propagating wave when reflection occurs?

The second law of reflection states that “the incident ray, the normal to the surface at the point of incidence and the reflected ray, all lie in the same plane”.

Diffusereflection

Q1: A ray of light is incident towards a plane mirror at an angle of 30° with the mirror surface. What will be the angle of reflection?

The Portable Handheld UV Light is a compact, easy-to-use tool for quick sanitisation and document verification, ideal for professional and personal use.

When light passes from a denser medium to a lighter medium at an angle more than the critical angle required for refraction, then the light is reflected back into the denser medium. This is a phenomenon called Total Internal Reflection. The light undergoing the total internal reflection also follows the ordinary laws of reflection for light as shown below:

The principle when the light rays fall on the smooth surface, the angle of reflection is equal to the angle of incidence, also the incident ray, the reflected ray, and the normal to the surface all lie in the same plane.

Correct answer: Option c. There is no loss of energy in absorption. If the plane wave is incident on a perfect dielectric, part of the energy is transmitted into the second medium and part of the energy is reflected back into the first medium.
