Dual Nature of Radiation and Matter
... We can now repeat this experiment with incident radiation of the same frequency but of higher intensity I2 and I3 (I3 > I2 > I1). We note that the saturation currents are now found to be at higher values. This shows that more electrons are being emitted per second, proportional to the intensity of i ...

... The moving rod forms a closed loop with the rails, and once the rod starts moving, the area of this loop increases with time. With a constant magnetic field, this means that the magnetic flux is increasing with time, and therefore there must be an induced voltage. Let the position of the rod be x, w ...

... The spot size for the same instrument in geostationary orbit would be 0.01m/1m * 36,000 km = 360 km. This very large spot size is a key reason why there are as yet no microwave instruments in geosynchronous orbit. Now suppose the wavelength were 1 micron (near-IR) and the aperture were 1 cm in diame ...

Time in physics
Time in physics is defined by its measurement: time is what a clock reads. In classical, non-relativistic physics it is a scalar quantity and, like length, mass, and charge, is usually described as a fundamental quantity. Time can be combined mathematically with other physical quantities to derive other concepts such as motion, kinetic energy and time-dependent fields. Timekeeping is a complex of technological and scientific issues, and part of the foundation of recordkeeping.
