This man tried to use mirrors to focus sunlight to burn enemy ships
Archimedes
What do B and A represent in the following image?
A- Angle of Incidence
B- Angle of Reflection
This type of lens bulges out on both sides and is used in magnifying glasses.
Double Convex Lens
This type of mirror curves inward
Concave
What does translucent mean?
Only some light is able to pass through
This greek philosopher/mathematician theorized that vision occurs when light beams came out of a person’s eyes and struck an object, thereby illuminating it.
Pythagoras
What does C represent in the Diagram?
The Normal Line
This type of lens caves inward on both sides.
Double Concave Lens
This type of mirror curves outward
Convex
Why can't you see a reflection if a mirror has a rough surface?
Because the light would scatter
This man proved that vision occurs when light bounces off objects and enters our eyes.
al-Haytham
The angle of incidence will equal the angle of reflection when the light bounces off of this kind of mirror.
A flat mirror
Who was the scientist that first used a microscope in a practical way?
Anton van Leeuwenhoek
This type of mirror causes light that hits it to diverge (spread apart).
Convex Mirror
What is the bending of light called and who was the scientist that first noticed this bend when light passed through different materials?
Refraction, Ptolemy
Somebody invented the telescope and then this dude heard about it, got mad, and invented his own version in just 1 day!
Galileo
If the angle of reflection is 62 degrees, when measured to the normal, how much would the angle of incidence be?
62 degrees
What branch of science did Anton van Leeuwenhoek eventually lead to the creation of?
Microbiology
Why would a security mirror in a store (one that allows you to see people further away in the store up closer), never use a concave mirror?
Concave mirrors would always flip the image if it appears behind the focal point.
How fast does light travel? To the nearest 100,000 km/s
About 300,000 km/s
Who invented the first microscope?
Hans & Zacharias Jansen
Describe two ways of making a shadow of your hand appear smaller on a wall?
Move your hand away from the light source
Move the light source away from your hand
Describe the difference between a refracting and reflecting telescope
Refracting: - uses lenses (2)
Reflecting: - uses mirrors
Who was the scientist that used a set up of mirrors to accurately measure and calculate the speed of light?
Albert A Michelson
What animal is King of the Jungle?
A Lion
