Which of the following statements are true statements about two-point light source interference patterns? Two-point light source interference patterns consist of alternating nodal and antinodal lines. If projected onto a screen, two-point light source interference patterns would be viewed as alternating bright and dark spots with varying gradients of light intensity in between. As the distance between the sources is decreased, the distance between the nodal and antinodal lines is decreased. As the wavelength of the laser light is decreased, the distance between the nodal and antinodal lines is decreased. A nodal point would be formed if a trough of one wave meets a trough of another wave. Antinodal points are points where the medium is undergoing no vibrational motion. Suppose point P is a point where a wave from one source travels a distance of 2.5 wavelengths before meeting up with a wave from another source which travels a distance of 3.5 wavelengths. Point P would be a nodal point. Suppose point Q is a point where a wave from one source travels a distance of 2 wavelengths before meeting up with a wave from another source which travels a distance of 3.5 wavelengths. Point Q would be a nodal point. Suppose point R is a point where a wave from one source travels a distance of 2 wavelengths before meeting up with a wave from another source which travels a distance of 3 wavelengths. Point R would be a nodal point. If the path difference for points on the first nodal line is 4 cm, then the wavelength would be 6 cm. (NOTE: the first nodal line is considered to be the first nodal line to the left or right from the central antinodal line.)

Question

Which of the following statements are true statements about two-point light source interference patterns?

Two-point light source interference patterns consist of alternating nodal and antinodal lines.
If projected onto a screen, two-point light source interference patterns would be viewed as alternating bright and dark spots with varying gradients of light intensity in between.
As the distance between the sources is decreased, the distance between the nodal and antinodal lines is decreased.
As the wavelength of the laser light is decreased, the distance between the nodal and antinodal lines is decreased.
A nodal point would be formed if a trough of one wave meets a trough of another wave.
Antinodal points are points where the medium is undergoing no vibrational motion.
Suppose point P is a point where a wave from one source travels a distance of 2.5 wavelengths before meeting up with a wave from another source which travels a distance of 3.5 wavelengths. Point P would be a nodal point.
Suppose point Q is a point where a wave from one source travels a distance of 2 wavelengths before meeting up with a wave from another source which travels a distance of 3.5 wavelengths. Point Q would be a nodal point.
Suppose point R is a point where a wave from one source travels a distance of 2 wavelengths before meeting up with a wave from another source which travels a distance of 3 wavelengths. Point R would be a nodal point.
If the path difference for points on the first nodal line is 4 cm, then the wavelength would be 6 cm. (NOTE: the first nodal line is considered to be the first nodal line to the left or right from the central antinodal line.)
