Homework Statement https://imgur.com/a/XySpV (If above image can't be seen.) Homework Equations KCL/KCL Rth=Vth/I The Attempt at a Solution Included in Screenshot. What I did was Open-Circuited the Load and use Nodal Analysis to find Voc Then, I shortcircuited the Load to find...

According to DeMorgan’s theorem (break the bar and change the sign), the complement of ܽa⋅b+c⋅d is a'+b'⋅c'+d' Yet both functions are 1 for ܾܽܿ abcd 1110. How can both a function and its complement be 1 for the same input combination? What’s wrong here?I honestly have no idea. I mean, shouldn't...

Homework Statement Metal Surface is illuminated with 200nm wavelength light. Work Function of this metal is 3.0eV and its electric potential is 5V lower than a point of infinity. Determine max K.E of photoelectrons, which are just emitted from the work surface. Homework Equations K.Emax= hf...

Oh yeah sheesh, it ends at 90 degrees. And yes, that would work. Thanks for the clarification, BvU.

Hello, BvU, thanks for replying. But I wouldn't know "m" goes how high? If I use m=0, m=1, m=2, I will get 6 angles, 3 from each wavelength. If I use m=3 too, I get more angles as the answer. So how many values of m should I use? The question didn't specify. I mean, technically there are an...

Homework Statement A point light source is used in a Double Slit experiment. The light source contains two wavelengths(500nm and 600nm). Separation of the two slits d=1mm. Two sets of interference fringes are formed on a screen. Find the angles θ where bright fringes are formed for both the...

Actually my question sounds sort of similar to this https://www.physicsforums.com/threads/double-slit-experiment-one-slit-covered-with-glass.522303/. When I think about it again, since each bright fringe is replaced by another bright fringe, it should means that it shifts by 1 wavelength. So...

Hmm but I don't have the distance between the slits and the wall.

I merely used: Thickness= λ/4n to obtain 8.65×10^-8 m

It's a conceptual question though.

Homework Statement Consider a double slit experiment with a light source of 540nm. Slit separation is 4mm. A thin glass plate is placed in front of one of the slit,, resulting in each bright fringe moving to the location of the adjacent bright fringe. Find the minimum thickness of the glass...

This is the second part of the question. First part asked for Brewster's Angle and the polarisation state(56.7degrees and Linear Polarisation)

Homework Statement Consider a beam of unpolarised light incident onto air from a crown-glass with a refractive index of 1.52. Given that the incident light intensity has a power of 10mW, find the minimum incident angle when the power of the refracted light becomes zero. Homework Equations I...

Wait- so it's linearly polarised right? Since the reflected light is polarised only perpendicularly hmm.

Well, the light is incident from the glass. And I suppose that we observe the completely polarised light reflected through air? Brewster's angle is an angle of incidence at which light with a particular polarization is perfectly transmitted through a transparent dielectric surface, with no...
