Properties and Behavior of Light

The video explores the dual nature of light, acting as both a wave and a particle. It covers key wave properties like wavelength and frequency, and explains how light's speed is constant. The visible spectrum is discussed, along with the broader electromagnetic spectrum. Light's particle nature is introduced through photons, with energy dependent on frequency. The video concludes with how light interacts with matter, emphasizing spectrum analysis to understand distant objects.

What unique property does light share with all matter?

• It does not interact with other matter.

• It can only be a wave.

• It can only be a particle.

• It acts as both a particle and a wave.

What is the term for the distance between two consecutive wave crests?

• Velocity

• Frequency

• Amplitude

How is the velocity of a wave calculated?

• By adding wavelength and frequency

• By multiplying wavelength and frequency

• By dividing wavelength by frequency

• By subtracting frequency from wavelength

What is the approximate speed of light in a vacuum?
