Wavelength and frequency are inversely proportional to each other. ... Even though the wave speed is calculated by multiplying wavelength by frequency, an alteration in wavelength does not affect wave speed. Rather, an alteration in wavelength affects the frequency in an inverse manner.

❤️Hello!❤️ This is simple question and easy to understand.

so first you use a formula to calculate frequency of the wave.

v _ stands for velocity a.k.a speed

f_ stands for frequency which you have to find.

(pronounced lemda)_ stands for wavelength.

Then you gonna place all your values according to you have in the formula as shown then solve for f.

Finally, you use the time formula

where

T_ is period a.k.a time which equal to the reciprocal of frequency or equal to 1/f.

Simply input your values according to the formula and you your answer as 0.5s Hope this helps!  ↪️ Autumn ↩️
