Electromagnetic Spectrum & Telescope RETAKE

Front

What is the electromagnetic spectrum?

Back

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

Front

Which type of electromagnetic radiation has the longest wavelength?

Back

Microwaves have the longest wavelength in the electromagnetic spectrum.

Front

What is a refractor telescope?

Back

A refractor telescope is a type of telescope that uses lenses to bend light and form images. It is known for distorting images due to the bending of light.

Front

What is light pollution?

Back

Light pollution is the excessive or misdirected artificial light that brightens the night sky, making it difficult to see stars and celestial objects.

Front

What was the mission of the Kepler Space Telescope?

Back

The mission of the Kepler Space Telescope was to discover exoplanets, which are planets outside our solar system.

Front

What is a wavelength?

Back

A wavelength is the distance between the tops of two consecutive waves in a wave pattern.

Front

What is the difference between a reflector and a refractor telescope?

Back

A reflector telescope uses mirrors to gather and focus light, while a refractor telescope uses lenses.

Front

What is frequency in the context of waves?

Back

Frequency is the number of waves that pass a given point in one second, measured in hertz (Hz).

Front

What type of electromagnetic radiation is used in microwave ovens?

Back

Microwaves are used in microwave ovens to heat food.

Front

What is the significance of the visible light spectrum?

Back

The visible light spectrum is the portion of the electromagnetic spectrum that is visible to the human eye, allowing us to see colors.
