The wavelength of a light wave can be calculated using the formula: wavelength = speed of light / frequency. Plugging in the values for speed of light (3.00 x 10^8 m/s) and frequency (6.42 x 10^14 Hz), we get a wavelength of approximately 467.1 nanometers.
Black light typically refers to ultraviolet (UV) light in the range of 315-400 nanometers. UV light below 315 nm is sometimes referred to as "black light" as well, but the most common understanding is in the 315-400 nm range.
To calculate the number of photons emitted by a 100W yellow lamp in 2 seconds, you can first find the energy of one photon using E = hc / λ, where h is Planck's constant, c is the speed of light, and λ is the wavelength (560 nm). Then divide the power of the lamp by the energy of one photon to find the number of photons emitted per second. Finally, multiply that value by 2 to get the total number of photons emitted in 2 seconds.
The first mechanical clocks were invented in the 14th century and typically used weighted mechanisms to power the movement of gears and hands. These early clocks relied on precise gear ratios to regulate the passage of time, and they were often housed in church towers. As the weights descended, they drove the gears to move the clock hands, allowing people to track the time throughout the day.
The first mechanical clocks were introduced in the 14th century. These early clocks were weight-driven and used gears and escapements to regulate the movement of the hands. Prior to this, timekeeping devices were primarily sundials or water clocks.
The mechanical clock was invented in the 14th century in Europe, with various inventors contributing to its development. Some notable figures include Richard of Wallingford and Galileo Galilei. Prior to this, sundials and water clocks were used to measure time.

1.9 x 10^14 light years is equivalent to 1.9 quadrillion light years.
2 to the 14th power is 32766.
According to the electromagnetic spectrum, Gamma Rays fall at the smaller end with wavelengths as short as 10 to the negative 14th power. Shorter wavelength particles may exist however would be at the subatomic level and have not been observed yet. Not that I know of at least.
100 to the 14th power is 1 with 28 zeros: 10,000,000,000,000,000,000,000,000,000, which can be written as 10 Octillion.
