no... frequency refers to the number of times something happens in a given amount of time, ie: hertz is full waves passing a point in a second.
however, since waves are additive, you can produce an "anti-wave" that in-effect cancels out a wave

Well you can say that the frequency of DC is constant or not?
Yes it is constant at Zero Frequency. No, DC or Direct Current only means that the current only goes one direction, but it can have a frequency. You can have a square wave, sawtooth wave or sine wave that never goes from positive to negative or negative to positive and it would be a direct current with a frequency.
What is the voltage wave form?
It is positive and negative signal in the frequency of wave form, the voltage of amplitude modulation, that carriers the signal of frequency.In the process of graph showing result ...
Why does the output frequency of a full wave rectifier double that of input frequency?
One cycle of the AC input consists of a positive half-cycle followed be a negative half cycle. The FW rectifier basically reverses the polarity of one of the half-cycles, so there are now two positive pulses per single input cycle, effectively doubling the frequency. Of course the rectifier may be wired for the opposite polarity, with two negative pulses per input cycle, but the same principle applies.
What measurement can vary with AC current by not DC current?
HZ. Hertz is the name given to the frequency of the alternating circuit. Direct current (DC) has no frequency since one wire is always positive and the other is always negative; but AC (Alternating Current) rapidly changes polarity, and does so at a rate that is defined by HZ.
How do you convert cellphone gsm frequency to another gsm frequency?
How do you convert cellphone gsm frequency to another gsm frequency?"
Can frequency of wave be negative?
No. Frequency is the number of times something happens, per unit time. If nothing happens, the frequency is zero. We cannot have a negative number of things happening.
Are there negative dimensions?
No, but dimensions can be to negative powers. For example, the dimension for frequency is [T-1].

Is punishment a reinforcer?
Punishment is not a reinforcer. there is Negative Punishment and Positive Punishment, and also Negative Reinforcement and Positive Reinforcement.*Negative Punishment is a consequence withdrawn following a response that causes a behavior to occur with less frequency.*Negative Reinforcement is a consequence withdrawn following a response that causes a behavior to occur with greater frequency.*Positive Punishment is a consequence delivered following a response that causes a behavior to occur with less frequency.*Positive Reinforcement is a consequence delivered following a response that causes a behavior to occur with greater frequency.
What is frequency of dc?
You can say DC voltage has a frequency of zero Hz.Because it is unidirectional in nature (may be positive or negative)
Does both positive and negative reinforcement increase the frequency of responses?
Yes, both do. Negative reinforcement is quicker but positive reinforcement is more permanent.
What is the physical significance of negative frequency?
just ony in analysis purpose its not practically possible
How do you make a frequency table of all negative numbers?
by counting the amount of numbers and puting them in a tally.
When the frequency in Hertz and the reactance positive or negative in Ohms are known can you determine component values such as inductance or capacitance?
Positive
In negative frequency-dependent selection such as in the study done on the water boatman insect the incidence of predation leads to an?
Increase in a rare genotype.
What is the direction of the current?
Current flows from negative to positive for DC. AC the direction changes with the sinewave. eg. AC a frequency of 60Hz the direction changes 120 times.
Do tuning bracelets work?
Based on my research, Electromagnetic radiation has a negative effect on the cells of the body because it disrupts their natural frequency. ... However, when our Tuning Bracelets come into contact with skin, they work to bring the body back to its natural frequency.
