Which one of the following could be the frequency of ultraviolet radiation?
Correct answer: D. 1.0 x 10^15Hz
- A. 1.0 x 10^6Hz
- B. 1.0 x 10^9Hz
- C. 1.0 x 10^12Hz
- D. 1.0 x 10^15Hz
Explanation
The frequency of ultraviolet radiation can indeed be around 1.0 x 10^15 Hz. Ultraviolet (UV) radiation has a higher frequency than visible light, which is why we can't see it with our eyes. It falls in the electromagnetic spectrum between visible light and X-rays. UV radiation has various applications, such as in sterilization, tanning, and even in some medical treatments.

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.
