Interference of two circular 6 cm away sources created waves with the same frequency and wavelength are 3 cm position caused interference is non point is away from the two sources periodically.
Origin circular wave away two sources 6 cm to create waves with equal frequency and wavelength 3 cm Position colliding a node that is positioned away from sources both periods.
The circular wave two sources 6 cm apart to create a wave with frequency rate and wavelength 3ซม. position of สอดเป็น insertion point node that is the position away from the source, both are stages.
