The Nature of Light: Nature of Electromagnetic Waves

In the late 1600s, Isaac Newton proposed that light behaves as particles. This was challenged by scientists who believed light travels in waves, as it can bend and pass through objects. This wave theory was dominant for many years. Over a century later, Albert Einstein introduced the concept of photons, suggesting light is made of energy packets. Today, it's accepted that light behaves both as waves and particles, acting like a wave when traveling and like particles when interacting with objects.

What was Isaac Newton's explanation for the behavior of light?

• Light is a combination of waves and particles.

• Light travels in waves.

• Light is a stream of tiny particles.

• Light is a form of energy.

Which characteristic of light supports the wave theory?

• Light is made of photons.

• Light travels in a straight line.

• Light can be absorbed by objects.

• Light can bend around objects.

Who proposed that light is made up of tiny energy packets called photons?

• Isaac Newton

• Albert Einstein

• Thomas Young

• James Clerk Maxwell

How does light behave when it is traveling?

• As a solid object

• As a stream of particles

• As a gas

• As a wave

What is the modern scientific consensus on the nature of light?

• Light is only a wave.

• Light is neither a wave nor a particle.

• Light behaves both as waves and particles.

• Light is only a particle.
