The beam angle in light is determined by measuring the angle at which light is distributed or emitted from a light source. This angle dictates how much area the light will cover and is particularly important for applications where focused or spread lighting is required. The beam angle is calculated using the formula: Beam?Angle = 2×arctan (Width/2×Distance) Or you could just ask us.

Consider a simple conceptual scenario: A 5 meter long beam fixed at both ends, subjected to a 10 kN axial point load applied 2 meters from the left end (as shown in the figure). What will be the support reactions? A) 5 kN at both ends B) 6 kN at the left end and 4 kN at the right end C) 4 kN at the left end and 6 kN at the right end Please note that this is a conceptual question, not a realistic scenario.

?? ???????? ???? ???????????????? ?????????????? ???????? and not ruin the performance 1) Use meandering It can decrease the space of the antenna while keeping the electrical length. 2) Increase dielectric constant of the substrate It will definitely make the antenna smaller, but be careful with the performance - it can degrade as well. 3) Use shorting pins/walls IFA is one example of using shoring pins - it requires only quarter wavelength to radiate on the given frequency. ? Do you know any other techniques to reduce antenna size while staying on the same frequency band?

For a collimated beam, the diffraction-limited focal spot size of a laser beam depends on its wavelength, the size of the beam at the lens and its M2 value. Use this simple calculator to determine your laser's diffraction-limited focal spot size, assuming an ideal lens without aberrations and a collimated laser beam. If the beam is not collimated, then the full Focal Spot Size Calculator should be used (set p to 0.01 and fill in λ, fl, θ, d). https://bit.ly/3SdKYbn

Density function representation Let's divide the coordinate system into a lattice (X0,Y0,Z0). We then operate on the grid points with the wave function so that for the transverse wave A = sin(k*(X0-v0*t)) the grid gets the values Y1 = Y0 + A.*dy. Correspondingly, for longitudinal wave motion B = sin(k*(X0-v0*t)) and X1 = X0 + B.*dx. Finally, the entire lattice flows upward: X0 = X0 - v*t and Y0 = Y0 - v*t. The same applies more generally. Instead of the function changing the value y = f(x), the function changes the lattice value x = x + f(x)*dx.
