In the case when the electrons lose all their kinetic energy (K.E.) in the first collision, the X-ray photon emitted has the following set of frequency and wavelength?
Correct answer: A. fmax , λmin
- A. fmax , λmin
- B. fmax , λmax
- C. fmin , λmax
- D. fmin , λmin
Explanation
fmax , λmin : This option suggests that when electrons lose all their kinetic energy in the first collision, the emitted X-ray photon will have maximum frequency ( fmax ) and minimum wavelength ( λmin ). According to the relationship between frequency and wavelength (c = λf, where c is the speed of light), as frequency increases, wavelength decreases. So, if the frequency is maximum, the wavelength should be minimum, and vice versa.

About Waves
Progressive waves transfer energy through oscillations, with wavelength, frequency, amplitude and wave speed related by v = fλ; sound speed depends on the medium. Superposition produces interference and stationary waves in strings and organ pipes, while simple harmonic motion describes the oscillation itself and must be distinguished from wave propagation.
