Particle of Light Energy

Front

What is a photon?

Back

A photon is a particle of light energy that is associated with every color detectable by the human eye.

Front

What is the speed of light in a vacuum?

Back

The speed of light in a vacuum is approximately 299,792 kilometers per second (km/s).

Front

What is the relationship between wavelength and frequency in light?

Back

The wavelength and frequency of light are inversely related; as the wavelength increases, the frequency decreases, and vice versa.

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, including visible light, radio waves, X-rays, and gamma rays.

Front

What is visible light?

Back

Visible light is the portion of the electromagnetic spectrum that is visible to the human eye, typically ranging from wavelengths of about 400 to 700 nanometers.

Front

What is the principle of wave-particle duality?

Back

Wave-particle duality is the concept that light and other forms of electromagnetic radiation exhibit both wave-like and particle-like properties.

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 is the role of photons in photosynthesis?

Back

Photons provide the energy required for photosynthesis, allowing plants to convert light energy into chemical energy.

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 is a spectrum?

Back

A spectrum is a range of different colors produced when light is dispersed, such as through a prism.
