- How many helium atoms, each with a radius of about 31 pm, must be placed end to end to have a length equal to one wavelength of 470 nm blue light?arrow_forwardTwo radio antennas separated by d = 3.00 102 cm. as shown in Figure P24.7, simultaneously broadcast identical signals at the same the signals. (a) If the car is at the position of the second maximum wavelength. A car travels due north along a straight line at position x = 1.00 103 m from the center point between the antennas and its radio receives the signal. (a) If the car is at the position of the second maximum after that at point O when it has traveled a distance of y = 4.00 102 m northward, what is the wavelength of the signals? (b) How much farther must the car travel from thus position to encounter the next minimum in reception? Hint: Do not use the small-angle approximation in this problem.arrow_forwardA circular radar antenna on a Coast Guard ship has a diameter of 2.10 m and radiates at a frequency of 14.0 GHz. Two small boats are located 8.00 km away from the ship. How close together could the boats be and still be detected as two objects? Need Help? Watch It Read Itarrow_forward
- An LED with total power Ptot=910 mW emits UV light of wavelength 370 nm. Assuming the LED is 45% efficient and acts as an isotropic point source (i.e., emits light uniformly in all directions), what is the amplitude of the electric field, E0, at a distance of 2.5 cm from the LED?arrow_forward(1) Write down the electric and magnetic fields for a monochromatic plane wave of amplitude Eo and frequency o traveling in free space in the negative x direction and polarized in the z direction. (ii) Sketch the wave and give the explicit Cartesian components of k and n. (iii) A reflective glass plate with refractive index n is placed in the yz plane at x = 0. Write down the electric field of the reflected wave from this glass plate.arrow_forwardPlane-polarized light is incident on a single polarizing disk, with the direction of E0 parallel to the direction of the transmission axis. Through what angle should the disk be rotated so that the intensity in the transmitted beam is reduced by a factor of each of the following?(a) 2.55 (b) 4.05 (c) 6.4arrow_forward
- Radiation from an X-ray source consists of two components of wavelengths 154.433 pm and 154.051 pm. Calculate the difference in glancing angles (2θ) of the diffraction lines arising from the two components in a diffraction pattern from planes of separation 77.8 pm.arrow_forwardGiven that 100 W/m? of a randomly polarized (unpolarized) light is incident normally on a stack of ideal linear polarizers that are positioned one behind the other with the transmission axis of the first vertical, the second at 30° from the vertical, the third at 60° from the vertical and the fourth at 90° from the vertical axis. How much light emerges after each polarizer?arrow_forwardA green laser emits a beam of wavelength 532 light nm in the air. The wavenumber k is : Select one : a) 1.880 x 106 rad m-1 b) 1.067 x 107 rad m-1 c)1.181 x 107 rad m-1 d) 6.701 x 107rad m-1arrow_forward
- A marine radar operating at a frequency of 9400 MHz emits groups of radio waves 0.0800 us in duration. Radio waves, like light waves, are electromagnetic in nature and travel at 3.00x10° m/s. Find (a) the wavelength of these waves; and (b) the length of each wave group, which is indicative of the precision with which the radar can measure distance.arrow_forwardThe wavelength of red light from a helium-neon laser is 633 nm in air and 479 nm in a medium of index of refraction n. The speed v and the frequency f of light in the given medium are: (Given: c = 3 x 10^8 m/s, and 1 nm = 10^-9 m) V = 2.64 x 10^8 m/s; f = 4.74 × 10^14 Hz v = 2.45 x 10^8 m/s; f = 4.74 × 10^14 Hz v = 2.27 x 10^8 m/s; f = 6.26 × 10^14 Hz v = 2.27 x 10^8 m/s;f = 4.74×10^14 Hz v = 2.64 x 10^8 m/s; f = 5.39 x 10^14 Hz v = 2.45 x 10^8 m/s; f = 5.80 × 10^14 Hzarrow_forwardA beam of light with wavelength 440 nm in air hits a thin piece of glass 10.28 microns thick (with refractive index 1.55) at an angle of 40.8 degrees to the normal. What is the path difference between the two reflections from the layers of the glass, in wavelengths? [Note to get the phase shift we multiply this number by 2π, but this is modulo 2π, i.e. any integer number of wavelengths are 2π phase shifts, equivalent to no phase shift... basically in terms of phase we only really need the non-integer part of your answer. Note also that for the phase shift we would need to add a π for the reflection off the glass-air interface.]arrow_forward
