Coherence; when two wave sources have a constant phase difference and the same
frequency, and the same waveform.
interference: phenomenon in which two waves superpose to form a resultant wave of
greater, lower, or the same amplitude.
Frequency= 75 Hz
Phase difference = 90 degrees
AB = 546*85*10^(-11)/0.13*10^(-3)
AB = 3.57 * 10^(-3) m
The blue light has lower wavelength than 546 nm, according to formula the distance
between the maxima is directly proportional to wavelength, so the distance will decrease
It shows the wave nature of light
monochromatic describes light that has the same wavelength so it is one color.
two wave sources are perfectly coherent if they have a constant phase difference and the
same frequency, and the same waveform.
To wear special glasses to protect eyes
Wavelength = 6*10^(-6)
If wavelength decreases, the distance between the maxima decreases too because
according to formula they are directly proportional
