The answer is B. A guitar generally produces sound waves that propagate when the strings are strummed. The strings are displaced through the vibrations caused by contact of the hand and the guitar. You will also notice the vibrations by looking closely to the string. Wave particles continuously collide with each other to make a sustaining or prolonging sound.

Answer:
Wavelength = 9.4×10⁹ m
Explanation:
Given data:
Frequency of radiation = 3.2×10⁻² Hz
Wavelength of radiation = ?
Solution:
Formula:
Speed of light = frequency ×wavelength
Speed of light = 3×10⁸m/s
Now we will put the values in formula.
3×10⁸m/s = 3.2×10⁻² Hz × wavelength
Wavelength = 3×10⁸m/s /3.2×10⁻² s⁻¹
Wavelength = 0.94×10¹⁰ m
Wavelength = 9.4×10⁹ m
