Sapting leng you have a string with a mass of 13.7 q. you stretch the string with a force of 8.39 n, giving it a length of 1.87 m. then you vibrate the string transversely at precisely the frequency that corresponds to its fourth normal mode, that is, at its fourth harmonic. what is the wavelength of the standing wave you create in the string? what is the frequency? wavelength number frequency: number hz

a)  

b)

Explanation:

Given:

String vibrates transversely fourth dynamic, thus n = 4

mass of the string, m = 13.7 g = 13.7 × 10⁻¹³ kg

Tension in the string, T = 8.39 N

Length of the string, L = 1.87 m

a) we know

where,

= wavelength

on substituting the values, we get

or

b) Speed of the wave (v) in the string is given as:

also,

equating both the formula for 'v' we get,

on substituting the values, we get

or

or

idk sorry i only needs point for apex

explanation:

low freq = 100 mhz

low wavelength =101.7m

length = 3x10^8/freq
