Awave is produced in a rope. the wave has a speed of 33 m/s and a frequency of 22 hz. what wavelength is produced? .
a. 0.67 m
b. 0.75 m
c. 1.5 m
d. 3.0 m

The correct answer to the question is C) 1.5 m i.e the wavelength of the wave produced on  the rope is 1.5 m.

CALCULATION:

As per the question, the wave is produced on a rope.

The speed of the wave is given as v = 33 m/s.

The frequency of the wave is given f = 22 Hz.

We are asked to calculate the wavelength of the wave.

The wavelength, speed and frequency of a wave are related as -

                                     ⇒  

                                                         [ans]

Hence, the wavelength of the wave is 1.5 m.

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer

snell's law

refractve index = sin incidence / sin refraction
