What is the 10 uses of concave mirror?
Concave mirrors are commonly used in torches, searchlights and headlights of vehicles to get powerful parallel beams of light. They are used as shaving mirrors to see a larger image of the face. Dentists use concave mirrors to view large images of the teeth of the patients.
Which mirror is used in dentist?
A concave mirror gives the dentist a magnified reflection of the mouth while also refracting a bit of light. This means the image in the mirror is larger, brighter, and, for the dentist, easier to see. Another plus of using a concave mirror is that the image in the mirror isn’t inverted.
How is the reflecting telescope used today?
A reflecting telescope is one that causes an image to reflect at a focus point by using mirrors. These telescopes improved the before used refracting telescopes by giving a clearer picture. Reflecting telescopes also allow larger objects to be seen and are therefore ideal for studying objects in our Solar System.
What are the pros and cons of a reflecting telescope?
Pros & Cons
| Pros | Cons |
|---|---|
| Large mirror = better light collecting capacity No chromatic aberrations (colored fringes around stars) Relatively low cost | Optical quality often disappointing Collimation and mirrors cleaning processes Open tube = high vulnerability to dust, humidity..etc Bulky and heavy |
What problem does a reflecting telescope solve?
Reflecting telescopes solve the problem of chromatic aberration, which often occurs with refracting telescopes.
