The thermal energy that is released from the bubble collapse is so great that it can cause weak light emission. [1] The mechanism of the light emission remains uncertain, but some of the current theories, which are categorized under either thermal or electrical processes, are Bremsstrahlung radiation, argon rectification hypothesis, [ 2 ] and ...
Among coral reef fish, sound detection and generation can span from 1 Hz to 200 kHz, while their hearing abilities encompasses frequencies within the range of 100 Hz to 1 kHz. [89] Several different types of anthropogenic noise are at the same frequencies as marine organisms in coral reefs use for navigation, communication, and other purposes ...
Experiment using two tuning forks oscillating at the same frequency.One of the forks is being hit with a rubberized mallet. Although the first tuning fork hasn't been hit, the other fork is visibly excited due to the oscillation caused by the periodic change in the pressure and density of the air by hitting the other fork, creating an acoustic resonance between the forks.
The top 10% brought home $248,600 or more, and a household income of at least $1.2 million put you in the top 1%. To figure out the typical net worth of someone at those different benchmarks, I ...
In modern parlance, if a string sounds the note C when plucked, a string twice as long will sound a C an octave lower. In one system of musical tuning, the tones in between are then given by 16:9 for D, 8:5 for E, 3:2 for F, 4:3 for G, 6:5 for A, and 16:15 for B, in ascending order. [6]

By definition, visible light is the part of the EM spectrum the human eye is the most sensitive to. Visible light (and near-infrared light) is typically absorbed and emitted by electrons in molecules and atoms that move from one energy level to another. This action allows the chemical mechanisms that underlie human vision and plant photosynthesis.
