Unit PHz
Name petahertz
Category Frequency
Details Petahertz (PHz) is a unit of frequency in the field of electromagnetic waves or oscillations. It denotes the measurements of frequency in extremely high frequency ranges, typically used to represent the frequency of light waves or other extremely high-frequency phenomena.

One petahertz (1 PHz) is equivalent to 1 x 10^15 Hertz (Hz), meaning that it represents 1,000,000,000,000,000 cycles or oscillations per second. The petahertz unit is quite significant in scientific and engineering applications such as ultrafast phenomena in physics, material science, and chemistry, which involve attosecond timescales and study of interactions at such high-frequency ranges.
