3.1 What is the minimum possible thickness of a soap bubble suppose it looks green (λ=500nm) when viewed at an angle of 45 degrees from the surface normal of the bubble? What is its color when viewed from the surface normal direction? Why the color looks grey before a soap bubble breaks? Suppose soap water has a refractive index of n=1.33 for all wavelengths of light. Na
An Optical Spectrometer. You and your team are tasked with characterizing an equilateral, triangular prism to be used in an optical spectrometer. An optical spectrometer contains a dispersive element (in this case, the prism) that separates an incoming beam of light into its constituent wavelengths (or colors), and a photocell that measures the intensity of each color (wavelength) by measuring the intensity of the dispersed light as a function of angle. The index of refraction of the prism material you are using depends on the wavelength as n(A)=(1.111 x 104 nm¹) A (nm) + 1.609 An incident beam of white light impinges on the surface (see drawing) at an angle of 42.2 degrees below the normal. The prism is in air (n = 1.000). Normal Ꮎ Red (660 nm) Violet (410 nm) (a) Relative to the prism base (i.e., the horizontal in the drawing), at what angle does red light (A-660.0 nm) emerge on the opposite side?

Shown at right are two boxes (mass m and 2m) attached to identical springs, and attached to each other by a string running over a pulley. The springs are initially neither stretched nor compressed and the masses are initially at rest. The blocks then speed up and eventually slow down again until each block has moved a distance s, at which point both blocks are momentarily at rest. Determine a symbolic expression in terms of given variables for the spring constant of each identical spring. No explanation necessary. We'll use the work-energy theorem with a system consisting of both blocks, the string, both springs, and the Earth. The net external work on this system is zero (the various normal forces all act on points of contact that are not moving). The initial and final kinetic energy for both blocks is zero because they are not moving 2m m ΔΕ = 0 ks² · − 0 + ¼½ks² − 0 + mgs − 0 + (−2mgs) − 0 = 0 k = mg S

The circuit below contains a battery and four resistors. The voltage across the battery is 11.6 V. In the circuit, the values of all the resistances are known. These resistances are R₁ = 4.9 2, R2 = 2.1 S2, R3 = 6.0 2, R4 = 7.2 S, and R5 = 3.5
Please step by step solutions
A desired (standard) temperature is set by adjusting a lever or wheel on the thermostat. A mechanism such as a bimetallic strip or bellows converts the actual temperature surrounding the thermostat into physical movement. When the variance between desired and actual temperature exceeds some design maximum, sensor movement creates an electrical contact that communicates a signal to the correcting entity, in this case the control of a furnace or air conditioner, and the variance is automatically corrected. The output of a system can be measured and the variance between measured and desired output is used to adjust the system. Which one of the following is the correct perspective of the timing control for an engineer? A O Concurrent control В. Feedforward C. O Feedback control Which statement is NOT true about McGregor motivation (leadership) 'Theory X'? А. Subordinates must be persuaded, rewarded, and punished by management В. Develop countries apply this theory for managing industry…
