Particle of Light Energy

Front

What term refers to a particle of light energy associated with every color detectable by the human eye?

Back

PHOTON

Front

What is the speed of light in a vacuum?

Back

Approximately 299,792 kilometers per second (km/s).

Front

What is the relationship between wavelength and frequency in light?

Back

Wavelength and frequency are inversely related; as wavelength increases, frequency decreases.

Front

What is the visible spectrum?

Back

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

Front

What is the principle of wave-particle duality?

Back

The concept that light exhibits both wave-like and particle-like properties.

Front

What is a photon?

Back

A quantum of light or a particle of light energy.

Front

What is the formula for calculating the energy of a photon?

Back

Energy (E) = Planck's constant (h) × frequency (f).

Front

What is the role of photons in photosynthesis?

Back

Photons provide the energy required for plants to convert carbon dioxide and water into glucose and oxygen.

Front

What is refraction?

Back

The bending of light as it passes from one medium to another due to a change in speed.

Front

What is the difference between reflection and refraction?

Back

Reflection is the bouncing back of light from a surface, while refraction is the bending of light as it enters a different medium.
