A sound wave with a frequency of 300 hertz is traveling through a medium at a speed of 320 meters/second. What is its wavelength? A.
18.8 meters
B.
0.510 meters
C.
1.07 meters
D.
20.6 meters

C (1.07 metres)

Explanation:

wavespeed = frequency x wavelength

rearrange for wavelength

wavelength = wavespeed ÷ frequency

so 320 ÷ 300 = 1.07m (rounded)

convex lenses are thicker at the middle. rays of light that pass through the lens are brought closer together (they converge). a convex lens is a converging lens. when parallel rays of light pass through a convex lens the refracted rays converge at one point called the principal focus.
