Annie's Module 15

Question 1

Define Electromagnetic wave. 🤷🏼‍♀️

Answer 1

A transverse wave composed of oscillating field and a magnetic field that oscillates perpendicular to the electrical field 🙋🏼‍♂️

Question 2

Light travels in waves only according to the wave theory of Huygens. Is this True or false?🤔

Answer 2

False. Light travels in little packages of waves. The wave theory is not correct alone nor is the particle theory alone. 🙋🏼‍♀️

Question 3

What is The Law of Reflection🤷🏼‍♀️

Answer 3

The Law of Reflection is: the angle of reflection equals the angle of incidence. 🙋🏼‍♂️

Question 4

What is Huygens theory of light? 🤔

Answer 4

Huygens considered light to be a wave. He said light was a wave instead of a particle. His theory is called the wave theory.🙋🏼‍♀️

Question 5

What was Newton’s theory of light?🤔

Answer 5

After studying light Newton concluded that a beam of light behaved the same as a stream of partials witch moved in the same direction. Newton’s theory is known as the particle theory.🙋🏼‍♀️

Question 6

What is the order of wavelengths for the colors of the rainbow? 🤷🏼‍♀️

Answer 6

The longest wavelength is red than orange, yellow, green, blue, indigo, and lastly violet. 🙋🏼‍♂️

Question 7

Light’s speed dose what?🤷🏼‍♂️

Answer 7

Light’s speed stays constant though all substances.🙋🏼‍♀️

Question 8

To produce light you only need electricity. True or false?🤔

Answer 8

False. You need electricity and magnetism because they work together to produce light.🙋🏼‍♀️
