I am not an expert, but I think that two of the same frequencies will make a larger frequency, while two frequencies that are exactly opposite of each other will cancel each other out.
While the above answer is correct it doesn't totally answer the question. To cancel out a frequency one has to introduce the same frequency 180 degrees out of phase with the frequency being canceled.
When adjacent signals overlap each other in the frequency domain resulting in interference of the signals, that is called CrossTalk.
Destructive interference, which causes the signals to cancel each other out. This results in a signal with an amplitude of zero.
Never, they always cancel each other
They do not cancel each other out. Each serves a different purpose in cooking and baking.
Balanced forces, that are of equal strength.
Optical beat interference occurs when two optical signals with slightly different frequencies interfere with each other, creating a beat frequency signal. This interference is commonly used in optical devices such as interferometers to extract information about the phase or frequency of the signals.
They react and cancel each other out. The process is called neutralization and it causes them to cancel out.
Forces that cancel each other out are called balanced forces.
The broadcast media are more regulated than print media because of the frequency. The frequency signal interferes with each other unlike print media, which doesn't have to worry about frequency signals.
If they cancel, then their magnitudes must be equal.
Forces that don't cancel each other out are called unbalanced forces. When two or more forces act in opposite directions and do not cancel each other completely, they create a net force that results in an acceleration of the object.
The speed of a wave doesn't depend on its frequency.REASON:According to the formulaV=frequency * Lambdaso,V/ Lambda= frequencyHere,Frequency is inversely proportional to the wavelength. so, If we increase the value of frequency then by same amount frequency will decrease and will cancel out the effect of each other the "V" will remain constant.
