EM Spectrum, Life Cycle of Stars, Big Bang

Front

What is the Electromagnetic Spectrum?

Back

The Electromagnetic Spectrum is the range of all types of electromagnetic radiation, which includes visible light, radio waves, microwaves, infrared, ultraviolet, X-rays, and gamma rays.

Front

What happens to energy as the frequency of electromagnetic waves increases?

Back

As the frequency of electromagnetic waves increases, the energy of the waves also increases.

Front

What is a Red Giant?

Back

A Red Giant is a late stage in the life cycle of a star, characterized by a large size and a reddish color, occurring after the star has exhausted the hydrogen in its core.

Front

What is a White Dwarf?

Back

A White Dwarf is a small, dense star that is the remnant core of a star that has exhausted its nuclear fuel and shed its outer layers.

Front

What is a Supernova?

Back

A Supernova is a powerful and luminous explosion that occurs at the end of a star's life cycle, particularly in massive stars, resulting in a dramatic increase in brightness.

Front

What is a Black Hole?

Back

A Black Hole is a region in space where the gravitational pull is so strong that nothing, not even light, can escape from it.

Front

What color of visible light has the longest wavelength?

Back

Red light has the longest wavelength of visible light.

Front

What is the Big Bang Theory?

Back

The Big Bang Theory is the leading explanation for the origin of the universe, proposing that it began as a singularity approximately 13.8 billion years ago and has been expanding ever since.

Front

What is the life cycle of a star?

Back

The life cycle of a star includes stages such as nebula, main sequence, red giant, supernova, and the formation of a white dwarf, neutron star, or black hole.

Front

What occurs during the collapse of a Red Supergiant's core?

Back

During the collapse of a Red Supergiant's core, a supernova explosion occurs, leading to the formation of either a neutron star or a black hole.
