Frequencies would show resonance will be 30 Hz,45 Hz and 60 Hz. Option B and E are correct.
What is resonance frequency?
Mechanical systems and charged particles all have a frequency that they vibrate at. this frequency is referred to as the resonance frequency or natural frequency.
When the matching vibrations of another item enhance the amplitude of an object's oscillations, this is known as resonance.
15 Hz is the fundamental frequency of the string.
Higher frequencies, such as the first overtone, second overtone, third overtone, and so on, must be used to cause the string to vibrate in a resonant manner.
F₁ = 2F₀ = 2 x 15 = 30 Hz is the initial overtone.
F₂ = 3F₀ = 3 x 15 = 45 Hz is the second overtone.
F₃ = 4F₀ = 4 × 15 = 60 Hz is the third overtone.
Hence,frequencies would show resonance will be 30 Hz,45 Hz and 60 Hz. Option B and E are correct.
