The frequency of an X-ray with a wavelength of 5.0 x 10^18 Hz can be calculated using the formula:
\[ f = \dfrac{c}{\lambda} \]
where:
\( f \) = frequency
\( c \) = speed of light (approximately 3.0 x 10^8 m/s)
\( \lambda \) = wavelength (5.0 x 10^18 Hz)
Plugging in the values, we get:
\[ f = \dfrac{3.0 \times 10^8 \, m/s}{5.0 \times 10^18 \, Hz} \]
\[ f = 6.0 \times 10^{-10} \, Hz \]
Therefore, the frequency of the X-ray with a wavelength of 5.0 x 10^18 Hz is 6.0 x 10^-10 Hz.
