The time elapsed since you stopped the stopwatch is 0.41 s.
<em>Your question is not complete, it seems to be missing the following information;</em>
"The velocity of the ant is 2 m/s"
The given parameters;
- velocity of the ant, v = 2 m/s
- change in position of the ant, Δx = 0.81 m
- initial time, t₁ = 4 s
- time when the ant was noticed, = t₂
Velocity is defined as the change in displacement per change in time of motion of an object.
The time elapsed since you stopped the stopwatch is calculated as;
Thus, the time elapsed since you stopped the stopwatch is 0.41 s.

Heya!!
For calculate wavelength, lets applicate formula:
<u>Δ Being Δ</u>
f = Frequency = 262 Hz
v = Velocity = 343 m/s
= Wavelenght = ?
⇒ Let's replace according the formula:
⇒ Resolving
Result:
The wavelength is <u>1,3 meters.</u>
Good Luck!!
