Answer:
An instrument takes the image that you are looking at and reflects it off the aluminum coating. The image then bounces off the coating to the glass. The glass is angle toward the eyepiece so that you have a full visual of the image you are trying to see. The telescope allows us to see further; they are able to collect and focus more light from distant objects than our eyes can alone. This is achieved by refracting or reflecting the light using lenses or mirrors.

Explanation:
Given
Temperature of solid ![T=500\ K](https://tex.z-dn.net/?f=T%3D500%5C%20K)
Einstein Temperature ![T_E=300\ K](https://tex.z-dn.net/?f=T_E%3D300%5C%20K)
Heat Capacity in the Einstein model is given by
![C_v=3R\left [ \frac{T_E}{T}\right ]^2\frac{e^{\frac{T_E}{T}}}{\left ( e^{\frac{T_E}{T}}-1\right )^2}](https://tex.z-dn.net/?f=C_v%3D3R%5Cleft%20%5B%20%5Cfrac%7BT_E%7D%7BT%7D%5Cright%20%5D%5E2%5Cfrac%7Be%5E%7B%5Cfrac%7BT_E%7D%7BT%7D%7D%7D%7B%5Cleft%20%28%20e%5E%7B%5Cfrac%7BT_E%7D%7BT%7D%7D-1%5Cright%20%29%5E2%7D)
![e^{\frac{3}{5}}=1.822](https://tex.z-dn.net/?f=e%5E%7B%5Cfrac%7B3%7D%7B5%7D%7D%3D1.822)
Substitute the values
![C_v=3R\times (\frac{300}{500})^2\times (\frac{1.822}{(1.822-1)^2})](https://tex.z-dn.net/?f=C_v%3D3R%5Ctimes%20%28%5Cfrac%7B300%7D%7B500%7D%29%5E2%5Ctimes%20%28%5Cfrac%7B1.822%7D%7B%281.822-1%29%5E2%7D%29)
![C_v=3R\times \frac{9}{25}\times \frac{1.822}{(0.822)^2}](https://tex.z-dn.net/?f=C_v%3D3R%5Ctimes%20%5Cfrac%7B9%7D%7B25%7D%5Ctimes%20%5Cfrac%7B1.822%7D%7B%280.822%29%5E2%7D)
what is it ill know your question??!!
