How are refracting and reflecting telescopes similar?

Refractors telescopes utilize specially designed lenses to focus the light on an image. A Reflector telescope uses mirrors, which causes light to reflect at different angles within the optical tube and extends the overall light path. Reflecting telescopes have many advantages as compared to refracting telescopes. In what way are the refracting telescope and reflecting

Why are Mars moons not round?

The moons are aspherical because gravity is too weak to overcome the rock stresses. Smaller moons are generally less spherical. The nearer moon, Phobos has less dust because it is nearer from Mars and is less able to gravitationally hold onto its residual dust from its cratering than Deimos. Why are the moons of Mars

How do you describe a graph in math?

What is a graph? In math, a graph can be defined as a pictorial representation or a diagram that represents data or values in an organized manner. The points on the graph often represent the relationship between two or more things. How do you describe a function on a graph? Use the vertical line test

What does the no hair theorem describe?

The no-hair theorem states that all black hole solutions of the Einstein–Maxwell equations of gravitation and electromagnetism in general relativity can be completely characterized by only three externally observable classical parameters: mass, electric charge, and angular momentum. What is the meaning of the statement that black holes have no hair? The no-hair theorem is the

What is covered in Calc 2?

Calculus II is the second course involving calculus, after Introduction to Calculus. Because of this, you are expected to know derivatives inside and out, and also know basic integrals. In this course, we will cover series, calculus in more than one variable, and vectors. What topics are covered in Calc 2? Calculus 2 Course summary.

Can you look at a lunar eclipse with a telescope?

You don’t need any special glasses to view a total lunar eclipse. From beginning to end, this celestial event is incredibly safe and simple to view. Even better news is that you can use binoculars and telescopes to look at the moon during a total lunar eclipse without having to worry about using special filters.
