Space & Light Flashcard 2024

Front

What are gamma rays?

Back

Gamma rays are a form of electromagnetic radiation with the shortest wavelengths and highest frequencies, making them highly energetic.

Front

What is the relationship between wavelength and energy in electromagnetic waves?

Back

Shorter wavelengths correspond to higher energy, while longer wavelengths correspond to lower energy.

Front

Which color of light has the highest energy?

Back

Blue light has the highest energy among visible light colors.

Front

What color does an object glow when heated to 5,000 K?

Back

An object heated to 5,000 K glows yellow.

Front

What happens to the color of an object as it cools from 5,000 K?

Back

As it cools, the color changes from yellow to orange to red.

Front

What is the range of visible light in nanometers?

Back

Visible light ranges from about 400 nanometers (blue) to around 700 nanometers (red).

Front

Define wavelength in the context of electromagnetic waves.

Back

Wavelength is the distance between successive peaks of a wave, typically measured in nanometers for light.

Front

What is frequency in relation to electromagnetic waves?

Back

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

Front

Explain the electromagnetic spectrum.

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, from gamma rays to radio waves.

Front

What is the significance of the color blue in terms of energy?

Back

Blue light has a shorter wavelength and higher energy compared to other visible colors.
