Sample interview questions: Can you explain the concept of gravitational lensing and its significance?
Sample answer:
Gravitational lensing is a phenomenon in which the path of light is bent due to the gravitational field of an intervening object. This can cause distant objects to appear distorted, magnified, or even multiple, as the light from the object is bent around the intervening object.
The strength of the gravitational lensing effect depends on the mass of the intervening object and the distance between the object and the light source. The larger the mass of the object, the stronger the lensing effect will be. Similarly, the closer the object is to the light source, the stronger the lensing effect will be.
