### Subject:Physics (Waves and Optics)

Question:

What is the difference between a real image and a virtual image?

Inactive
Anysa R.

A real image is created when light actually emerges from that place in space. A virtual image is created when light appears to emerge from the image, but does not actually. What type of image is created depends on whether the mirror or lens is converging or diverging, as well as whether the object is placed inside or outside of the lens/mirror's focal point.

Question:

What are the factors that may be useful to identify before solving a fluid mechanics problem (as outlined by the Bernoulli Equation)?

Some potential factors you should look for can come from answering these questions: 1.) Is there a pressure difference across the two points you are referencing in your fluid system? -If yes, write that difference down. -If no, write down that the change in pressure is 0. 2.) Is there a difference in height between the two points you are referencing in your fluid system? -If yes, write that difference down. -If no, write down that the change in gravitational potential energy density is 0. 3.) Is there a difference in cross-sectional area between the two points you are referencing in your fluid system? -If yes, write that difference down. -If no, write down that the change in kinetic energy density is 0. 4.) Is there a pump in between the two points you are referencing in your fluid system? -If yes, write down that the energy from pump per volume is (the given number). -If no, write down that the energy from the pump per volume is 0. 5.) Is there any resistance between the two points you are referencing in your fluid system? -If yes, write down that the dissipation (meaning current (I) x resistance (R)) is the product of those two values. -If no, write down that the dissipation is 0. Finding out these important components will allow you to construct a complete Bernoulli equation, and set you up for a correctly solved fluid mechanics problem. *Note: Often, you will be asked to solve for one of the components above by using the others in the equation. Thus, if you do not have one of the answers to the questions above yet, that is OK! This is likely the purpose of the problem.

Question:

When you receive your class syllabus at the beginning of a new semester, what should you do?

When you receive your class syllabus, it is a good idea to not just read through it, but to take time to write down important dates or deadlines on your calendar. This would include things like test dates, office hour times, or due dates for assignments. Then, schedule in study time devoted to that class in your weekly routine. Make this time mandatory, and hold yourself to that requirement. This will ensure that you do not miss any important deadlines, and that you will be preparing yourself along the way, minimizing chance for procrastination. Different individuals will have study techniques that work best for them, but until we are able to work together to figure out what your preferred learning style is, the steps I have outlined above are a great starting point.
