Question

two point sources are generating periodic waves in phase. the wavelength is 4.0 cm. a point on the second antinodal line is 30.0 cm from the nearest source. how far is this point from the farthest source?

Answer 1

The distance between the two point sources is 60.0 cm.

Step-by-step explanation:

To find the distance between the two point sources, we can use the concept of path difference. The second antinodal line is 30.0 cm from the nearest source, which means it is at a distance of half the wavelength from the nearest source. The wavelength is given as 4.0 cm, so the distance between the two sources is twice the distance from the second antinodal line to the nearest source, which is 2 × 30.0 cm = 60.0 cm.

Answer 2

The point on the second antinodal line is 30.0 cm from the nearest source. The distance between the point and the farthest source is 60.0 cm.

Step-by-step explanation:

The point on the second antinodal line is 30.0 cm from the nearest source. Since the wavelength is 4.0 cm, each antinode is half the wavelength apart. Therefore, the distance between the two point sources is twice the distance from the point to the nearest source, which is 2 × 30.0 cm = 60.0 cm.
