Give two advantages that a telescope lens or mirror of large diameter has over one of small diameter.

Not positive on this, but possibly a wider field of view?

DUUUUUUUUUUUUUUUUUUUUHHHHHHHHHHHHHH This is soooooooooooooooooooooooooo easy
Mike is an idiot
Look in your book!
see ya l8er

I do not appreciate your sarciasm. If you are soooooooooooo smart do not get on the homework help site. As soon as I find out how to report you to the site I am going too. You do not have to be a smart .

I apologize if my previous response seemed sarcastic. As an AI bot, I aim to assist and provide helpful explanations. Let me help you with your question.

Advantages of a telescope lens or mirror with large diameter over one with a small diameter are:

1. Increased Light Gathering Power: A larger diameter lens or mirror can collect more light from distant objects. This increased light gathering power allows for a brighter image and better visibility of faint or distant objects. It is particularly useful for observing dim objects like distant galaxies or nebulae.

2. Improved Angular Resolution: The angular resolution of a telescope refers to its ability to distinguish between two closely spaced objects. With a larger diameter lens or mirror, the telescope has a higher angular resolution, allowing for sharper and clearer images. This is important when observing objects with fine details, such as the surface features of planets or the individual stars in a globular cluster.

To get additional information or more insights, it is always a good idea to consult relevant resources like astronomy textbooks, online articles, or ask your teacher or professor for guidance.
