Description
- Task 3.7
- The current strength in the oscillatory circuit varies according to the law I = 0.1 sin 103t A. The inductance of the circuit is 0.1 H.
- Find the law of voltage change on the capacitor and its capacitance.
- Task 3.17
- The oscillating points are removed from the source of oscillations by a distance of 0.5 and 1.77 m in the direction
- Propagation of the wave. The phase difference of their oscillations is equal to 3/4. The oscillation frequency of the source is 100 s -1.
- Determine the wavelength and the speed of its propagation.
- Task 3.27
- Normally monochromatic light falls on a thin glass wedge. The smallest thickness of the wedge, s
- Which show interference fringes in reflected light, is 0.12 μm. Distance between
- With strips of 0.6 mm. Find the angle between the surfaces of the wedge and the wavelength of light, if the exponent
- Refraction of glass 1.5.
- Task 3.37
- What should be equal to the width of the grating with a period of 10 μm, so that in the spectrum of the second
- Order was resolved doublet? 1 = 486.0 nm and? 2 = 486.1 nm?
- Task 3.47
- What is the angle between the main planes of the two polarizers, if the intensity of light,
- Passed through them, decreased by 5.3 times? To consider that each polarizer reflects and absorbs
- 13% of the light incident on them.
- Task 3.57
- The Cherenkov counter from the rock salt is a beam of relativistic electrons with a kinetic
- Energy of 0.511 MeV. Determine the angle of the light cone solution.
- Task 3.67
- The density of the energy flux in the laser pulse can reach 1020 W / m2.
- Determine the pressure of such radiation normally incident on the black surface.
- Task 3.77
- As a result of Compton scattering by a free electron, the energy of the gamma-photon decreased by three
- Times. The photon scattering angle is 60 °. Find the kinetic energy and momentum of the recoil electron. Before
- Collision the electron rested.
