- What is the maximum velocity of electrons ejected from a material by 61 nm photons, if they are bound to the material by 4.79 eV?A 100-W incandescent light bulb produces about 4% of it's enegy asvisible light. Assuming that the light has an average wavelength of 510 nm, calculate how many such photons are emitted per second by a 100-W incandescent lightbulb.The most common fluorescent lightbulbconverts ultraviolet light from mercury atoms to white light. If anultraviolet photon of wavelength 185 nm is emitted by a mercuryatom and absorbed by the phosphor, what is the maximum number of red 655-nm photons that the phosphor can emit?
- Hello, Can I please have help regarding this problem ? Thanks. Suppose that the clock on our lecture room has a minute-hand length of 10 cm.(Use a coordinate system with the origin at center of clock and +x axis along the3PM direction and the +y direction along the 12PM direction). From the 12 to 8mark, for the tip of the minute hand:a) Sketch a vector diagram labeling ri, rf, Δr, Vi, Vf, and ΔV.b) Calculate the displacement vector in unit-vector notation.c) Calculate the average velocity vector in unit-vector notation.d) Calculate the average acceleration vector in unit-vector notation.e) Calculate magnitude and direction of the average acceleration vector.f) Calculate the magnitude and direction of the total acceleration of the tip ofthe minute hand at the 6 mark.Problem A small helium-neon laser (λ=632.8 nm) produces a light beam with an average power of 3.5 mW and a diameter of 2.4 mm.
