Multiple Choice
X-Ray detectors are devices that use scintillators to convert X-rays into light in order to detect X-Rays indirectly. Which of the following would be picked up by an X-Ray detector:radiation with a wavelength of 0.85 nm or a frequency of 6.52 x 1011 s-1?
A
radiation with a wavelength of 0.85 nm
B
radiation with a frequency of 6.52 x 1011 s-1
Verified step by step guidance1
Understand that X-ray detectors are designed to detect X-ray radiation, which typically has wavelengths ranging from 0.01 to 10 nanometers (nm).
Identify the given options: one is a wavelength of 0.85 nm, and the other is a frequency of 6.52 x 10^11 s^-1.
Recognize that the wavelength of 0.85 nm falls within the typical range for X-rays, suggesting it is likely to be detected by an X-ray detector.
To determine if the frequency corresponds to X-ray radiation, use the relationship between frequency (ν), wavelength (λ), and the speed of light (c): c = λν. Rearrange to find the wavelength: λ = c/ν.
Calculate the wavelength for the given frequency using the speed of light (approximately 3.00 x 10^8 m/s) and compare it to the X-ray wavelength range to see if it falls within the detectable range.
