Which explains why the sky is blue?

• Blue light is not easily scattered by the atmosphere

• Blue light is not easily absorbed by the atmosphere

• Air molecules scatter blue light more readily than other colors

• Blue light is reflected off the world's oceans into the atmosphere

Which statement best describes the 'Law of reflection'?

• The angle of incidence is equal to the angle of reflection

• The angle of reflection is perpendicular to the normal.

• The angle of reflection is parallel to the angle of incidence

• Both the angle of incidence and reflection lie in different planes.

It Is also known as curving of space-time.

• Black hole

• warping

• Bending

• orbiting

How does special relativity differs from general relativity?

• Special relativity applies only to moving frames while general relativity applies only to stationary frames.

• Special relativity applies only to stationary frames while general relativity applies only to accelerating frames.

• Special relativity applies only to stationary or moving frames while general relativity applies only to accelerating frames.

• Special relativity applies only to accelerating frames while general relativity applies only to stationary or moving frames.

Which is true about time according to general relativity?

• Time slows down with gravity.

• Time accelerates with gravity.

• Time is pulled down by gravity.

• Time can't be changed by gravity.

He was the one to first use the general relativity in predicting that a sufficiently massive body can deform space-time and that lead to his idea of the existence of black holes.

• Karl Schwarzschild

• Albert Einstein

• Thomas Young

• Max Planck

What force is explained by general relativity?

• Weak nuclear force

• Electromagnetic force

• Strong nuclear force

• Gravitational force

How does the curvature of space-time affect the light from distant stars?

• The curvature of space-time reflects light passing through it.

• The curvature of space-time bends light passing through it.

• The curvature of space-time does not allow light pass through it.

• The curvature of space-time absorbs the light passing through it.
