Kepler space telescope

The Kepler space telescope was launched by NASA to discover Earth-like planets orbiting other stars

Telescopes

This animation shows optical and radiotelescopes used in astronomical observation

The reflection and refraction of light

A ray of light is reflected or refracted at the boundary of two mediums with different refractive indices.

Optical illusion

The information gathered by the eye is misinterpreted by the brain.

The human eye

The eye is one of our most important sense organs. When stimulated by light, electric impulses are produced by its receptors.

Vision correction

Concave and convex lenses are used for the correction of short-sightedness and far-sightedness.

Observatory

Observatories are often built at high elevations to minimise the effects of atmospheric turbulence

Optical isomerism

Mirror image isomers of asymmetrical shapes and solids are non-superimposable.

The mechanism of vision

The curvature of the lens of the eye changes when we look at a distant or at a near object, to ensure a sharp image.
