Optics Quiz

Refraction of light occurs when light travels from one medium to another, causing a change in its speed and direction. An example of its application in everyday life is the bending of a straw in a glass of water.

A concave lens forms a virtual, erect, and diminished image of an object. This property is significant in corrective lenses for individuals with nearsightedness, as it helps to diverge the incoming light rays and bring the image into focus on the retina.

The wavelength of the incident light

The angle of refraction

The intensity of the incident light

The refractive indices of the two media involved (correct)

<p>Total internal reflection occurs when a propagating wave strikes a medium boundary at an angle larger than a particular critical angle. An example of its use in optical fibers is in telecommunications, where it allows for the transmission of signals over long distances with minimal loss of signal strength.</p> Signup and view all the answers
