About 1013 millibars would equal about... 30 inches------------_______________*****************
The frequency is 30 per second, or 30 'Hertz'.
Just remember that the period is the reciprocal of the frequency.
The frequency is 720Hz
30%
An X-ray has a frequency in the range 30 petahertz to 30 exahertz, that is 30×1015 Hz to 30×1018 Hz.

The frequency is 30 per second, or 30 'Hertz'.
300 million * 100 thousand = 3*108*105 = 3*1013 = 30*1012 = 30 trillion.
30 MHz to 300 MHz
High Frequency
An X-ray has a wavelength in the range of 10 to 0.01 nanometers. The frequency is in the range of 30 petahertz to 30 exahertz, that is 30×10^15 Hz to 30×10^18 Hz.
An X-ray has a wavelength in the range of 10 to 0.01 nanometers. The frequency is in the range of 30 petahertz to 30 exahertz, that is 30×10^15 Hz to 30×10^18 Hz.
The frequency of x-ray in the range 30 petahertzto 30 exahertz (3 × 1016 Hz to 3 × 1019 Hz) and
Wavelength = speed/frequency = 30/10 = 3 meters
Just remember that the period is the reciprocal of the frequency.
The frequency can't be 30 Mhz 30 Mhz is a ham radio frequency but to calculate the wavelength, devide 300 by the frequency in Mhz that will give you 10 meters (300/ƒ)
