telescopes
what is the appropriate telescope timeline of the inventors
Hans Lippershey
Galileo's
Johannes Kepler
what types of lense does a reflecting telescope have
mirror lense
list 5 parts of the microscope
base
ocular lense
diaphgram
nose peice
objective lenses
true or false White light contains all colors
true
what is light
is electromagnetic radiation that can be seen by the eye
what did Hans Lippershey do to help invent the telescope
first refractor telescope (to help with military defense)
which telescope has 2 types of lenses
hybrid
what are the colors of the rainbow
roygbiv
what happens within shorter wave lengths of light
Higher frequency
Higher energy
what are other examples of electromagnetic radiation that cant be detected by the bare human eye
x-rays
infrared rays,
which scientist was the first to use the telescope for astronomy
Galileo's
how do binoculars work
Binoculars manipulate light with prisms and lenses
what was Isaac newtons large discovery about light
observed that white light is made up of all the colors of the rainbow
what happens within longer wavelengths of light
Lower frequency
Lower energy
where are images formed within the eye
the retina
how did Johannes Kepler enhance Galileo's telescope
by placing two convex lenses that produce an upside-down image. Kepler's design is still used in today's refractor telescopes
how are prisms effective in binoculars
Play the role like a mirror in order to place the image in the right place
what happens when white light passes through a prism
red light is refracted less than orange, which is refracted less than yellow, etc ... and a spectrum (rainbow) results
what is frequency
is the number of waves that pass one point per second
what colors are the cones in the eyes sensitive to
blue light
red light
green light
what are the three types of telescopes
refractor telescope
reflector telescope
hybrid telescope
how are lenses effective in binoculars
Magnifies the object, but they place it upside down
true or false Color is a property of visible light
true
what is the measurement for frequency
Hertz (Hz)
what does it mean to be colorblind
is the condition that results when you have a problem with one (or more) of your cones
