Intensity power relation
Nettet5. mar. 2024 · Antenna directivity and gain. The far-field intensity \( \overline{\mathrm{P}}(\mathrm{r}, \theta)\) [W m-2] radiated by any antenna is a function of direction, as given for a short dipole antenna by (10.2.27) and illustrated in Figure 10.2.4. Antenna gain G(θ,φ) is defined as the ratio of the intensity P(θ,φ,r) to the intensity … Nettetwhere P is the power carried by the wave through area A.

Nettet2. The energy of these electrons (i.e., their velocity once they leave the metal) does not depend on the light intensity, although the total number of electrons does depend on intensity (rather unusual). 3. If the light frequency is lowered below a certain value (which depends on the type of metal used), then NO electrons are observed (very very
NettetIntensity of a wave is the average rate of energy transfer per unit area perpendicular to the direction of the propagation of the wave. It's the same as the average power … table cloverNettetYes, the intensity depends, in part, on the frequency. Intensity is power per unit area. Power is energy per time. For a photon, the energy is $h\nu$. So, the intensity will be $$I=Nh\nu / A$$ if $N$ is the monochromatic photon emission rate (photons per second), $\nu$ is the frequency of the photons, and $A$ is the area these photons are hitting. table clusteringNettetWhat is the relation between intensity and energy in case of photoelectric effect? If intensity is energy per unit area per unit time then how kinetic energy of photoelectron is constant with increasing intensity of light and it increases when frequency of light is increased, as we know energy of light is directly proportional to frequency of light and … table clusters in oracleNettet12. sep. 2024 · The power supplied from the battery is equal to current times the voltage, P = I V.
