Final answer:
The frequency of dental X-rays with a wavelength of approximately 1.10 x 10^-10 m, using the speed of light in the formula c = λf, is calculated to be approximately 2.727 x 10^18 Hz. The closest answer provided is (a) 1.10 x 10^18 Hz.
Step-by-step explanation:
The student has asked about the frequency of dental X-rays given a wavelength of approximately 1.10 x 10^-10 m. To find the frequency, we can use the formula for electromagnetic waves: c = λf where c is the speed of light (3.0 x 10^8 m/s), λ is the wavelength, and f is the frequency. By rearranging this formula to solve for frequency (f = c/λ), we can compute the frequency of the X-rays.Plugging in the values, we get: f = (3.0 x 10^8 m/s) / (1.10 x 10^-10 m) which calculates to approximately 2.727 x 10^18 Hz. However, none of the options exactly matches this value. Considering the approximate nature of the calculations and the options provided, the closest answer would be (a) 1.10 x 10^18 Hz, which seems to be a rounded version.
