What is optics problem: Definition and 59 Discussions
In physics, physical optics, or wave optics, is the branch of optics that studies interference, diffraction, polarization, and other phenomena for which the ray approximation of geometric optics is not valid. This usage tends not to include effects such as quantum noise in optical communication, which is studied in the sub-branch of coherence theory.
Hi,
My Question:
A beam of light is emitted in a pool from a depth of 62.0 cm. Where must it strike the air-water interface, relative to the spot directy abovie, in order that the light does not exit the water?
My Work
Tan(49)=(x/62.0cm), got 49 degrees from the textbook where...
I need to find a Fermat Equation for a parabola that sends light from a point sour ce on X the access back parrallell to the x access.
Thanks
If you want to see what I tried, I posted a pic a few days ago, under the title optics, but no one responded at that point.
Hey Everyone..
I'm having trouble with this question, I think I have this question figured out but my answer is coming out incorrect... Tell me if there is a flaw in my logic.. question is:
"Suppose that a luminous star of radius R1=1.74×108 m is surrounded by a uniform atmosphere...
If anyone who's good at optics/physics can help me with this electromagnetic part of optics...it'll be great.
so here's the problem:
imagine an electromagnetic wave with it's E-field in the y-direction. Show that (dE/dx)=-(dB/dt) applied to the harmonic wave B
E=Eo cos(kx - wt)...
Please help with optics problem!
I was wondering if anyone could help me out with the following optics problem:
A prism, ABC, is configured such that angle BCA = 90 degrees and angle CBA = 45 degrees. What is the value of the index of refraction if, while immersed in the air, a beam...
Can anyone explain to me why there is still a diffraction pattern observed even if the light is slightly converging when it hits the diffraction grating
Would appreciate anyhelp to solving any of these questions ty.
1 A diffraction grating of pitch 3 .27mm is illuminated at normal incidence with
light comprised of various wavelengths. If components of wavelength
495nm, 625nm and 990nm are present find:-
a) the angular positions of the...
I am having some trouble with this one...any help would be appreciated.
A 31.8cm focal length converging lens is 21.6cm behind a diverging lens. Parallell light strikes the diverging lens. After passing through the converging lens, the light is again parallel. What is the focal length of...
Ok I'm working on my geometric optics homework and this is the last problem and I can't seem to get it right.
An 6 astronomical telescope has a 32 cm focal-length objective lens. After looking at stars, an astronomer moves the eyepiece 1.0 cm farther away from the objective to focus on nearer...
