So I have an assignment and I have no idea how to solve it. Our professor is worse at physics then half of the students so more or less 90% of the people aren't able to solve. (everyone has a different task so I can't take someone else's and send it) That's why I need your help. Here are the two tasks that need to be done.
E: Oh, and my deadline is in 28 hours.
1)
Two sferic mirrors, one concave, with a curvature radius of 25cm and one convex mirror, with a curvature radius of 50cm are set one facing another so their principal axis match. The distance between their vertices is 50cm. The object is set in the middle between the mirrors. A small curtain is blocking the light from falling directly onto the convex mirror and because of that the image is first created on the concave mirror and then on the convex mirror.
a) Where is the image of the object and what are its properties?
b) Where would the image be if we use a flat mirror instead of the convex one.
This also need to be solved graphically.
2)
This is the equation of an electromagnetic wave in vacuum.
What are the frequency, wave lenght, period, initial phase and the expression for the associated magnetic field (written both as vectors and by components)? What is the average value of the intensity of this electromagnetic wave?
Please don't come here just to boost your post count, because I really need help.
Thanks in advance and I'm sorry if I used a wrong expression for something.
