EM Radiation and its features

Front

What happens to visible light when an object appears black?

Back

All 7 colors of the visible light spectrum are absorbed.

Front

What type of wave does not require a medium to travel?

Back

Electromagnetic waves.

Front

Why do sunrises and sunsets display a variety of colors like purples, reds, and oranges?

Back

The light hits the Earth at a shallower angle, passing through more air and causing more colors to scatter.

Front

If an object appears blue, what does this indicate about the colors of light?

Back

All colors are absorbed except blue, which is reflected.

Front

What type of waves are used to penetrate solids and create medical images?

Back

X-rays.

Front

What is the visible light spectrum?

Back

The range of electromagnetic radiation that can be seen by the human eye, typically from about 380 nm to 750 nm.

Front

What is scattering in the context of light?

Back

The process by which light is forced to deviate from a straight path due to interaction with particles or molecules.

Front

What is absorption in terms of light and color?

Back

The process by which an object takes in light energy, preventing it from being reflected or transmitted.

Front

What is the relationship between wavelength and color in visible light?

Back

Different wavelengths correspond to different colors; shorter wavelengths are blue/violet, while longer wavelengths are red.

Front

What is the role of the atmosphere in the color of the sky?

Back

The atmosphere scatters shorter wavelengths of light (blue) more than longer wavelengths, making the sky appear blue.
