Which of the following is an example of atmospheric refraction?
The twinkling of a star is due to atmospheric refraction of starlight as the starlight undergoes continuous refraction before it reaches the earth.
What is atmospheric refraction explain with two examples?
1) The apparent random wavering or flickering of object seen through a turbulent stream of hot air rising above a fire or a radiator. 2) Twinkling of stars. 3) Advanced sunrise and delayed sunset.
What is atmospheric refraction and what are the effects of it?
The refraction of light caused by earth’s atmosphere is called atmospheric refraction. Twinkling of stars, advanced sunrise and delayed sunset, apparent flattening of the sun’s disc at sunrise and sunset, and the change in the apparent position of stars all are effects of atmospheric refraction.
Where is refraction technology used in the real world?
Microscope or Telescope The lens of a telescope or microscope uses a refraction of light to make things look closer than they really are. The lenses of the telescope and microscope are curved in such a way that they magnify small objects or those far away so the human eye can see them.
Why is atmospheric refraction important?
This refraction is due to the velocity of light through air decreasing (the refractive index increases) with increased density. Atmospheric refraction near the ground produces mirages. Such refraction can also raise or lower, or stretch or shorten, the images of distant objects without involving mirages.
Which of the following is not an application of atmospheric refraction?
Explanation: The sun appears red at sunset not because of the atmospheric refraction of light but because of the scattering effect of light.
What is the importance of atmospheric refraction?
Atmospheric refraction is considered in measuring the position of both celestial and terrestrial objects.
What are some applications of reflection and refraction that we encounter in our daily lives?
A microscope uses a mirror to reflect light to the specimen under the microscope. An astronomical reflecting telescope uses a large parabolic mirror to gather dim light from distant stars. A plane mirror is used to reflect the image to the eyepiece. Parabolic mirrors are used in torches and car headlamps as reflectors.
What are the applications of reflection?
Side-view mirrors: The side-view mirrors of cars are made up of a convex mirror. When rays of light strike the surface of the mirror, it bounces back and helps the driver to see objects on the sides and behind the car.
Is Rainbow An example of atmospheric refraction?
Following are the application of atmospheric refraction: Advance sunrise and delay sunset. The apparent position of stars. Formation of rainbow.
Which of the following is caused by atmospheric refraction?
The phenomena of atmospheric refraction are: twinkling of stars. early Sunrise. delayed sunset.
