What is Wavelength?

Back

Wavelength is the distance between two consecutive peaks (or troughs) in a wave. It is a key concept in understanding wave properties.

Front

What is Net Force?

Back

Net force is the total force acting on an object after all the individual forces are combined. It determines the object's motion.

Front

What type of galaxy has ongoing star formation?

Back

Spiral galaxies are known for ongoing star formation, while elliptical galaxies do not typically have new stars forming.

Front

What is an Irregular Galaxy?

Back

An irregular galaxy is a type of galaxy that does not have a distinct regular shape, unlike spiral or elliptical galaxies.

Front

What is an Elliptical Galaxy?

Back

An elliptical galaxy is a type of galaxy characterized by an elongated shape and a lack of significant star formation.

Front

What is a Spiral Galaxy?

Back

A spiral galaxy is a type of galaxy that has a flat, rotating disk containing stars, gas, and dust, along with a central concentration of stars known as the bulge.

Front

What is the difference between Spiral and Elliptical Galaxies?

Back

The main difference is that spiral galaxies have ongoing star formation, while elliptical galaxies do not.

Front

What is Amplitude in a wave?

Back

Amplitude is the maximum extent of a wave's oscillation, measured from the rest position to the peak (or trough).

Front

What is Crest in a wave?

Back

Crest is the highest point of a wave, while the trough is the lowest point.

Front

What is a Trough in a wave?

Back

Trough is the lowest point of a wave, opposite to the crest.
