EM Spectrum and Space Exploration Flashcard

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.

What are X-rays used for in medicine?

Back

X-rays are used by doctors to create images of the inside of the body, helping to detect broken bones and other medical conditions.

Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, with the strength of the force depending on the mass of the objects and the distance between them.

Front

How does gravity on the Moon compare to gravity on Earth?

Back

Gravity on the Moon is less than that on Earth, which means objects weigh less on the Moon.

Front

What are gamma rays?

Back

Gamma rays are a type of electromagnetic radiation with the shortest wavelength and the highest frequency, making them very high in energy.

Front

What does NASA stand for?

Back

NASA stands for National Aeronautics and Space Administration.

Front

What is the wavelength of a wave?

Back

Wavelength is the distance between successive crests of a wave, often measured in meters.

Front

What is frequency in terms of waves?

Back

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

Front

What type of electromagnetic waves can be seen by the human eye?

Back

Visible light is the type of electromagnetic waves that can be seen by the human eye.

Front

What is the relationship between wavelength and frequency?

Back

Wavelength and frequency are inversely related; as the wavelength increases, the frequency decreases, and vice versa.
