- 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.
- 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.
- Wavelenght
- Wave Characteristics to know.
- 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.
- 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.
- A refracting telescope uses two lenses.
- Reflecting
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.
- A virtual image cannot be shown on
a screen.
- In a virtual image, the rays of light appear
to come from an image but do not actually
come from that image.
