Answer:

 λ₂ = 1.8 m

Explanation:

given,

wavelength of the string 1 = 0.90 m

frequency of the string 1 = 600 Hz

wavelength of string 2 = ?

frequency of the string 2 = 300 Hz

we now,

f\ \alpha\ \dfrac{1}{\lambda}

now,

\dfrac{f_1}{f_2}=\dfrac{\lambda_2}{\lambda_1}

\dfrac{600}{300}=\dfrac{\lambda_2}{0.9}

λ₂ = 2 x 0.9

 λ₂ = 1.8 m

Hence, the wavelength of the second string is equal to  λ₂ = 1.8 m

Which describes a high frequency wave?
SCORPION-xisa [38]
I think the correct answer from the choices listed above is option A. A high frequency wave is a wave with a low level of energy and a high pitch. Frequency is the number of waves passing per second of time. Hope this answers the question.
