What is the Doppler effect in relation to light?

Back

The Doppler effect causes the wavelength of light to change based on the relative motion of the source and observer.

What is the significance of blue shift in astronomy?

Back

Blue shift indicates that an object is moving toward the observer, causing its light to shift to shorter wavelengths.

What is the significance of red shift in astronomy?

Back

Red shift indicates that an object is moving away from the observer, causing its light to shift to longer wavelengths.

What is the formula for gravitational force?

Back

F = G * (m1 * m2) / r^2, where F is the gravitational force, G is the gravitational constant, m1 and m2 are the masses, and r is the distance between their centers.
