Why do light waves with the same wavelength and constant phase difference interfere with eacher to produce light and dark interface patterns?

If their phase difference is constant, then they don't produce light and dark
patterns. Light spots are produced where the two sources are in phase, and
dark spots where they're out of phase.

What are coherent sources and conditions for it?
Coherent sources are sources of light with a constant phase difference. The conditions for this are that there is a constant phase difference and that the light is of the same wavelength.
How can you double the frequency of a wave if you have control over both the wavelength and the wave velocity?
You can either halve the wavelength, keeping the wave speed constant; or double the wave speed, keeping the wavelength constant.
What are the significance of hartmanns' constant?
Hartman's constant is used to determine the wavelength of absorption spectrum of kmno4
What is the difference between constant and non-constant motion?
Acceleration is the difference between constant and non-constant motion.
When the freuency of a wave traveling at constant speed increases what decreases?
The Wavelength.
What are coherent sources and conditions for it?
Coherent sources are sources of light with a constant phase difference. The conditions for this are that there is a constant phase difference and that the light is of the same wavelength.
How the constructive interference occurs?
coherent waves are waves of the same frequency (same wavelength) and constant phase difference.
How are the frequency and the wavelength of a wave traveling at a constant speed related?
frequency = speed of wave / wavelength so if speed is constant then frequency varies inversely with wavelength
How can you double the frequency of a wave if you have control over both the wavelength and the wave velocity?
You can either halve the wavelength, keeping the wave speed constant; or double the wave speed, keeping the wavelength constant.
How does wavelength change when frequency is constant?
the wavelength changes when the frequency changes if the wavelengths are smaller and thinner then the frequency is high, when the frequency is slow then the wavelengths is larger and wider. if the frequency is constant then the wavelength is a normal size
What is the principle difference between radio waves and visible light?
Both of these are part of the electromagnetic spectrum. The main difference between the two is the wavelength and frequency. (Frequency multiplied by Wavelength always equals the Speed of Light, the constant abbreviated as "c". This is approximately equal to 186,000 miles per second or 300,000 km per second. If you know the wavelength and you want to find the frequency, divide "c" by the wavelength. )
What happens when you increase the speed of a wave what happens to the wavelength?
If the frequency remains constant, then the wavelength increases.
If a wave is moving at a constant speed and the wavelength is doubled what will happen to the frequency?
IF a wave moving at a constant speed were to have it's wavelength doubled (Wavelength x 2), then the frequency of the wave would be half of what it originally was (Frequency / 2).
If the speed of a wave doubles while the frequency remains the same what happens to the wavelength?
The wavelength stays constant.
What are the significance of hartmanns' constant?
Hartman's constant is used to determine the wavelength of absorption spectrum of kmno4
How is wavelength related to frequency for a wave traveling at a constant speed?
The product of its wavelength multiplied by its frequency is always equal to its speed. I think that's true even if the speed is not constant.
Because c the speed of electromagnetic radiation is a constant the wavelength of the radiation is....?
The wavelength is inversely proportional to its frequency. That is, as the frequency increases, the wavelength decreases and vice versa.
