#REAL VS VIRTUAL IMAGE DRIVER#

The light is diverging from a virtual image. After refraction through the lens, the light is diverging from a point where the photons have never visited. As before, light diverges from the real object, but no light converges to a real image. Real photons of light depart from a real object, and real photons of light arrive at a real image.įigure II.3 shows a lens forming a virtual image of a real object. Light diverges from a real object and it converges to a real image. A virtual object, however, may take one by surprise – so let’s look at all of them hereįigure II.2 shows a lens forming a real image of a real object, and I think it requires little explanation. Most people have no trouble understanding what a real object is or the distinction between a real image and a virtual image. Glass has refractive index μ with respect to air and the critical angle for a ray of light going from glass to air is θ.\).A glass prism of refractive index 1.5 is immersed in water (refractive index 4/3).

A small object is placed 50cm to the left of a thin convex lens of focal length 30cm.

An electromagnetic radiation of frequency n, wavelength λ, travelling with velocity v in air.

The angle of incidence for a ray of light at a refracting surface of a prism is 45∘.

Which of the following is not due to total internal reflection?.

When a point object is seen by an observer through a glass slab, the image is:…..

The container contains two immiscible liquids A(μ=1.4)…

The bottom of a container is of a 4.0cm thick glass slab.

Two plane wavefronts of light, one incident on a thin convex lens and another on the refracting face….

A prism is made up of material of refractive index √33.

Let D1, and D2 be angles of minimum deviation…

The refractive index of glass is 1.520 for red light and 1.525 for blue light.

The instrument used by doctors for endoscopy works on the principle of….

The refractive index of the diamond is…..

The critical angle for total internal reflection in diamond is 24.5.

The communication using optical fibers is based on the principle of…..

The angle of minimum deviation for a prism is 40∘ and the angle of the prism is 60∘.

An example of a virtual image is a side mirror in vehicles.

A common example of a real image is a projection lens in a projector.

The size of a real image and a virtual image can be smaller or larger than the actual object depending upon the distance of the object from the mirror or lens.

A real image is formed by only a concave mirror whereas a virtual image can be formed by concave, convex and plane mirror.

A real image formed is inverted while a virtual image formed is erect.A real image can be presented on screen while the virtual image can not be presented on screen.A real image is formed due to the convergence of light rays while the virtual image is formed due to the divergence of light rays.

The convex mirror used in the side mirror of vehicles shows the driver the road behind him. The projector lens fitted in the projector converges the image on a screen The virtual image can not be presented on a screen under any circumstances, as there is no actual convergence of light rays happening. Moreover, this is the only way by which we can see real images. The real image can be presented on the screen. The light rays don’t actually meet anywhere, but it is perceived that they meet somewhere behind the mirror. The light rays actually converge or meet at a fixed point. The real image formed is always inverted. The size of the image formed depends upon the distance at which the object is placed from the lens or mirror. A real image is an image that is created by the convergence of light rays, after reflecting/refracting from a mirror or lensĪ virtual image is an image that is created by the divergence of light rays, after reflecting/refracting from a lens or mirror.
