Electromagnetic Waves and Light Waves

Front

What is the definition of electromagnetic waves?

Back

Electromagnetic waves are waves that can travel through the vacuum of space and consist of oscillating electric and magnetic fields.

Front

What is the wavelength of a wave?

Back

The wavelength is the distance between two consecutive peaks or troughs in a wave.

Front

What is amplitude in the context of waves?

Back

Amplitude is the height or depth of a wave, determining how much energy the wave carries.

Front

What happens to light when it passes from air into water?

Back

Light bends when it passes through water, causing objects to appear displaced.

Front

Which color of light has the highest energy?

Back

Violet light has the highest energy in the visible spectrum.

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another, such as from air to water.

Front

What is reflection in terms of light waves?

Back

Reflection is the bouncing back of light waves when they hit a surface.

Front

What is the visible spectrum?

Back

The visible spectrum is the range of wavelengths of light that can be seen by the human eye, typically from red to violet.

Front

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

Back

Longer wavelengths correspond to lower energy, while shorter wavelengths correspond to higher energy.

Front

What is total internal reflection?

Back

Total internal reflection occurs when light hits a boundary at a steep angle and reflects entirely back into the medium.
