What is the consequence of using a telescope designed for ultraviolet light to observe visible light?.
- A.It will enhance the brightness of the observed objects.
- B.It will provide a clearer image of the objects.
- C.It will not effectively focus the visible light.
- D.It will increase the resolution of the images.
Model answer
What a good answer should say
- It will not effectively focus the visible light.
Explanation
Why this works
Using a telescope designed for ultraviolet light to observe visible light will not effectively focus the visible light due to the different optical requirements for each wavelength. This results in suboptimal image quality and limits the effectiveness of the observations, underscoring the importance of appropriate telescope design for specific wavelengths.
