The duck always creates oscillations in the water with a frequency of 2.0 Hz. Under what conditions for wave speed and boat velocity will the wavelength of waves generated by the duck be 2.5 m and
the wavelength of waves observed by the man in the boat be 1.9 m? (Adjust all three sliders to achieve
the conditions above. Assume that the duck is moving rightward with a positive velocity).

c. magnitude and direction

there are no components of a physical goal mentioned on the list of choices that you've provided.

you'd use the equation that establishes a relationship between  energy  and  wavelength, which looks like this

e=h⋅cλ, where

λ  - the wavelength of the photon; c  - the speed of light, usually given as  3⋅108m/s; h  -  planck's constant, equal to  6.626⋅10−34j s

plug the value you were given for the energy of the photon in the above equation to get the wavelength

e=h⋅cλ⇒λ=h⋅ce

λ=6.626⋅10−34js⋅3⋅108ms−1.257⋅10−24j=1.581⋅10−1m

its a circle not a square that's simple silly.
