(a) Human eyes detect only a very small band of the electromagnetic spectrum. However, some animals and insects see in higher and lower frequency bands than humans do. For this discussion, first do some research to find three examples of animals or insects that see in higher or lower frequency bands.
Then, in your initial discussion post, address the following:
- What were the examples that you found? Did they see in lower or higher frequency bands? List the specific wavelengths used by the animals/insects you chose.
- Were you surprised by the information that you found? Why or why not?
(b) In your initial discussion post, identify the pros and cons of using mirrors versus lenses in each of the following applications:
- a large, ground-based, astronomical telescope
- a small “spy” scope
- a terrestrial telescope designed only to read license plates
