REFRACTING TELESCOPES
What is a Refracting telescope?
The role of a refracting telescope is to magnify objects, This is done by refracting the light rays it receives to create a image that is inverted and magnified.
When it comes to refracting telescopes there are quite a few different types of refractor telescopes, some examples are are the astronomical telescope, however, they consist of similar
Components and parts.
Refractor telescopes always have 2 lenses, these are the objective lens, and finally the eye lens.
The objective lens is bigger allowing it to collect more light, and bring it to focus at the focal point, The more light it can collect the brighter it can display the magnified image to the eye, making it easier to see. The objective lens also commonly has a longer focal length than the eye

Its role is to magnify the collected light from the objective lens and direct it to your eye. Something to note is that both lenses are convex. This makes the final image be inverted. But allows for the most light to be collected, and that light to be directed at the focal point of lens, making a brighter and clearer image to be displayed.
For these telescopes, it is crucial that the are contained inside of a tube, to make sure that no other rays of light, or dust can enter which would affect the image. And to make sure the lenses are situated the correct length from each other, the distance between both of the lenses is equal to the length of both of the focal points. Another job the tube that conceals them has is to make sure they stay perfectly aligned to how they must correctly sit.
So to summarise, Three essential must-have components for a refracting telescope are the convex object lens, the convex eye lens, and the tube that situates them apart at the right alignment and distance specific to the

Astigmatism is an off axis aberration which caused the vertical line to appear clearer when observing the USAF target. This occurs when the beam of light converges more rapidly along the tangential direction compared to that of the sagittal direction, thus changing the beam profile from a circular one to a more elliptical one. Because the tangential focus is reached before the sagittal focus, the elliptical beam is compressed into a straight perpendicular line.

When researching for scholarly reviewed article on film, I used the University Library research browser to find academic journals; at first I had done research on magazine articles about Netflix Original Series “Luke Cage”. Later, I realized that these were not fitting for this assignment, I returned to the University Library search base and searched for academic articles

Light falling normally on the plates will be reflected back out with a phase difference. Figure 3: Apparatus set up for finding the thickness of an optical fibre, showing the optical fibre between the two glass plates This is due to the fact that some of the coherent light waves were reflected from the top plate and others from the bottom, this path difference resulted in the interference of these waves with one another. This caused an interference pattern similar to the below image: Figure 4: Image similar to the observed interference pattern.
