What happens when a sound wave encounters an obstacle in its path? A sound wave’s wavelength allows it to pass through objects.

Sound waves bend around the corners of obstacles.

Sound waves can easily pass through any object.

A sound wave’s amplitude allows it to move around objects.

Two students, each riding bicycles, start from the same apartment building and ride to the same building on campus, but each takes a different route. the first student rides 1100 m due east and then turns due north and travels another 1430 m before arriving at the destination. the second student heads due north for 1930 m and then turns and heads directly toward the destination.at the turning point, how far is the second student from the destination?
