A reflecting telescope is an optical telescope which uses a combination of curved or plane mirrors to reflect light and form an image, rather than lenses to refract or bend light to form an image It is usually used for astronomical purposes.


Hope this helps (:

The image is formed by the objective mirror ... the big one at the bottom end of the telescope. To SEE the image, you can put an eyepiece an inch or two behind it, or a piece of film or a CCD to capture it.

You're using a monochromatic beam of light with wavelength 500 nm in an interferometer. What is the minimum distance you would n
xxTIMURxx [149]

Answer:

The minimum distance moved by mirror is 125 nm

Explanation:

Given:

Wavelength of light \lambda = 500 \times 10^{-9} m

Here given in question, spot of constructive interference change to a destructive interference.

Hence minimum distance moved by one of mirror is given by,

   t = \frac{1}{2}(\frac{\lambda}{2} )

Where t = distance moved by mirror

   t = \frac{\lambda }{4}

   t = \frac{500\times 10^{-9} }{4}

   t = 125 \times 10 ^{-9}

Therefore, the minimum distance moved by mirror is 125 nm

A bungee jumper jumps from a tall bridge that is 60m above a flat, dry creek bed. She is carrying an audio generator that emits
dolphi86 [110]

Answer:

Explanation:

The original frequency of sound  f₀

The apparent frequency of sound fa

For apparent frequency the formula is

fa =  f_0\times\frac{V+v}{V-v }     , v is velocity of jumper which increases as he goes down .

Beat frequency

= fa - f₀

=  f_0\times(\frac{V+v}{V-v }-1)

=  f_0\times(\frac{2v}{V-v })

since v is very small in comparison to V , velocity of sound , in the denominator , v can be neglected.

beat frequency = f_0\times(\frac{2v}{V })

v , the velocity of jumper will go on increasing as long as net force on the jumper is positive or

mg > kx where x is extension in the cord and k is its force constant . Below this point kx or restoring force becomes more than weight of the jumper and then net force on the jumper directs upwards. At this point beat frequency becomes maximum.
