Light waves(DV)

Introduction

Buckle your seatbelts, ladies and gentleman, because in this WebQuest you are about to learn what is Light waves well enough to compete with your fellow students or maybe even your professor. There are only few steps to become smarter or maybe just revise the information you already knew before. I advise you to pay close attention to information and complete the given tasks.

 

 

 
This WebQuest is made only for educational purposes.

Task

Your task is:

  1. To watch video (below);
  2. To complete quiz about the video provided on the next page;
  3. To count your points after you are done with answering questions;
  4. To educate yourself.

Please click the "Process" tab on the left side of the screen to see what is next for you to complete. 

Process

According to the video you have just finished watching, determine whether these statements are True(T) or False(F)

  1. All kinds of light is visible to human eye.

  2. The are 2 types of waves - small and big.

  3. If you know the wavelenght or frequency of a light wave, you can also figure out it's energy.

  4. Long wavelenghts have high energies.

  5. Special receptors such as rods and cones helps us see colors and measure brightness.

  6. Blue color is defined as low-energy light.

  7. The light that has a short wavelenght does not get absorbed by human eye's surface.

  8. The visible light to human eye is between radiowave wavelenght and x-ray wavelenght.

  9. Many human-built devices can detect light outside the visible range of our eye.

  10. There are no space telescopes yet in the orbit, but will be in the future.

Evaluation

You get 1 point for each correct answer. The maximum points you can get is 10. The correct answers are listed below. 

1. Question: All kinds of light is visible to human eye.

     Answer: False (Human eye is not able to see such light waves as x-rays, microwaves and radio waves)

2. Question:The are 2 types of waves - small and big.

    Answer: True 

3. Question: If you know the wavelenght or frequency of a light wave, you can also figure out it's energy.

    Answer: True

4. Question: Long wavelenghts have high energies.

    Answer: False (Long wavelenghts have low energies)

5. Question: Special receptors such as rods and cones helps us see colors and measure brightness.

    Answer: True 

6. Question: Blue color is defined as low-energy light.

    Answer: False (The low-energy light is red)

7. Question: The light that has a short wavelenght does not get absorbed by human eye's surface.

    Answer: False (Actually it does get absorbed)

8. Question: The visible light to human eye is between radiowave wavelenght and x-ray wavelenght.

    Answer: True

9. Question: Many human-built devices can detect light outside the visible range of our eye.

    Answer: True

10. Question: There are no space telescopes yet in the orbit, but will be in the future.

     Answer: False (There are about 20 space telescopes in our orbit)
