Understanding the Nature of Light

What was the main idea behind Isaac Newton's corpuscular theory of light?

• Light is made up of small particles called corpuscles.

• Light is a continuous wave.

• Light is a form of energy.

• Light is a combination of waves and particles.

What did Thomas Young's experiment demonstrate about the nature of light?

• Light behaves like a stream of particles.

• Light travels in a straight line.

• Light is unaffected by obstacles.

• Light exhibits wave-like interference patterns.

Which of the following is a characteristic of a wave?

• It cannot interfere with other waves.

• It has a frequency and wavelength.

• It travels in a straight line.

• It is made up of particles.

What is the term used for the particles of light?

• Electrons

• Photons

• Neutrons

• Protons

How is the energy of a photon related to its frequency?

• Energy is inversely proportional to frequency.

• Energy is equal to the square of the frequency.

• Energy is directly proportional to frequency.

• Energy is unrelated to frequency.
