Behaviors of Waves

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another, caused by a change in its speed.

Front

What happens to light when it strikes a denser medium?

Back

When light strikes a denser medium, it slows down and bends towards the normal line.

Front

What is the normal line in the context of refraction?

Back

The normal line is an imaginary line perpendicular to the surface at the point of incidence where light strikes.

Front

What is the difference between reflection and refraction?

Back

Reflection is the bouncing back of light when it hits a surface, while refraction is the bending of light as it passes through different media.

Front

What determines the angle of refraction?

Back

The angle of refraction is determined by the indices of refraction of the two media involved, according to Snell's Law.

Front

What is Snell's Law?

Back

Snell's Law states that n1 * sin(θ1) = n2 * sin(θ2), where n is the index of refraction and θ is the angle of incidence or refraction.

Front

What is the index of refraction?

Back

The index of refraction is a measure of how much light slows down in a medium compared to its speed in a vacuum.

Front

How do filters affect the color of light?

Back

Filters absorb certain wavelengths of light and transmit others, which changes the color of the light that passes through.

Front

What color will an object appear under white light if it reflects only green light?

Back

The object will appear green under white light.

Front

What is the role of wavelength in color perception?

Back

Different wavelengths of light correspond to different colors; shorter wavelengths appear blue, while longer wavelengths appear red.
