Absorption spectroscopy refers to spectroscopic techniques that measure the absorption of radiation, as a function of frequency or wavelength, due to its interaction with a sample. The sample absorbs energy, i.e., photons, from the radiating field. The intensity of the absorption varies as a function of frequency, and this variation is the absorption spectrum. Absorption spectroscopy is performed across the electromagnetic spectrum.
A typical hurricane is about 300 miles across while a typical hurricane eye is 20 to 40 miles across.
For a low frequency source, the voltage across the inductor tends to zero because its impedance is proportionnal to source frequency, whereas the voltage across the resistor tends to the voltage source value.
The meniscus, which is a C-shaped cartilage in the knee joint, acts as a shock absorber and cushion between the femur and tibia. Its role is to distribute the load evenly across the joint and provide stability during movement.
Frequency interleaving is a technique where consecutive symbols in a data stream are spread across different frequency subcarriers in a communication system. This helps combat frequency-selective fading in wireless channels by reducing the impact of frequency-specific signal impairments. By spreading the symbols across multiple frequencies, frequency interleaving helps improve robustness and reliability of the communication link.

Yes, far more. The typical tornado is a few hundred feet across. The typical hurricane is a few hundred miles across.
When an LC tank is excited at the resonant frequency, the energy across each will be equal (but not necessary equal at a given moment in time). If excited at a frequency other than the resonant frequency, the impedance of the inductor (wjL) and capacitor (1/wjC) will not be equal, therefore energy across each will be different.
The size of a typical granule seen in the photosphere is about 1000 km across.

requires the input of energy and a carrier protein to move nutrients across a concentration gradient
The photodiode's voltage drop varies with the temperature and current flowing through it. The typical voltage drop (VBIAS - VREF) across the MAX4007 series is 0.8V, with a guaranteed maximum of 1.1V.
