- Waves
- Wave Characteristics to know.
- Wavelenght
- The Wavelenght of a wave is the
distance from a point on one wave to
the same point on the next wave,
measured in meters.
- The Wavelenght of a wave is the
distance from a point on one wave to
the same point on the next wave,
measured in meters.
- Amplitude
- The Amplitude of a wave is the
maximum distance of a point on
the wave from its rest position,
measured in metres.
- The Amplitude of a wave is the
maximum distance of a point on
the wave from its rest position,
measured in metres.
- Frequency
- Wave frequency is the number of
waves passing a point each second. It
is measured in hertz (Hz). A frequency
of 1 Hz means 1 wave passing per
second.

- Telescopes
- Reflecting
Telescopes
- A Reflecting Telescope
uses a lens and two mirrors.
- Secondary Mirror
- Primary Mirror
- Eyepiece Lens
- Secondary Mirror
- Reflecting Telescopes are a type of
optical telescope that uses one or more
mirrors to reflect light, forming an image.
- As reflecting telescopes use
mirrors, they are also called
'Catoptric Telescopes'.
- A Reflecting Telescope
uses a lens and two mirrors.
- Refracting Telescopes
- A refracting telescope uses two lenses.
- The Eyepiece Lens
- This lens is placed at
the 'Focal Point'.
- This lens is placed at
the 'Focal Point'.
- The Objective Lens
- The distance from the Focal
Point to the Objective Lens is
called the 'Focal Length'.
- This lens is also
known as a
'Convex Lens'.
- The distance from the Focal
Point to the Objective Lens is
called the 'Focal Length'.
- The Eyepiece Lens
- How they work
- In a refracting telescope, a convex lens
(the objective lens) creates an image
inside the tube and the eyepiece lens is
used to magnify the image.

Telescopes
- Lenses
- Many optical devices use
converging lenses t produce
images that are magnified.
- The magnification of converging lenses
depends on how curved their surfaces are
and how close together they are placed.
- Some images can be shown on a screen.
- Some images can be shown on a screen.
- The magnification of converging lenses
depends on how curved their surfaces are
and how close together they are placed.
- This is the different from a
virtual image, like that seen in
a mirror.
- In a virtual image, the rays of light appear
to come from an image but do not actually
come from that image.
- A virtual image cannot be shown on
a screen.

good source however, geocentric model is what we don't believe in, ptolemy created this theory hundreds of years ago where the Earth was in the middle and all of the planets orbited it and the sun. the heliocentric model was created by copernicus in the 16th century afterwards when he saw that Galalieo's obsevations of the telescope were disproving the geocentric model. he found that the sun was being orbited and the earth was not in the middle. this is the theory we believe in. this mind map needs some editing...
