Question

1. which wave diffracts the most when encountering an obstacle? (1 point) a wave with the longest wavelength a longitudinal wave a surface wave a wave with the highest amplitude

Explanation:

Diffraction is related to the wavelength of a wave. The greater the wavelength relative to the size of the obstacle, the more significant the diffraction. Long - wavelength waves diffract more than short - wavelength waves when encountering an obstacle. Longitudinal, surface waves, and amplitude are not directly related to the amount of diffraction in the context of this question.

Answer:

a wave with the longest wavelength
