Which part of the wave should be changed to alter its frequency?

To alter the frequency of a wave, you need to change the wavelength.


How do you alter the brightness of a bulb?

You alter the brightness of a bulb by changing the voltage or frequency that is applied to the bulb.

What is the frequency of a grasshopper?

They have a low frequency. Grasshoppers can also alter their sound to stay in tune to specific noises they come in contact with.


Example of evidence that frequency of light does not change upon reflection?

When light is reflected off a mirror, the frequency of the light does not change because reflection is a process that does not alter the properties of the light wave. The frequency of light corresponds to its color, and when we see our reflection in a mirror, we observe the same color that was emitted towards the mirror.


What effect does frequency have on the amplitude of a wave?

Frequency does not have a direct effect on the amplitude of a wave. The amplitude of a wave is determined by the energy of the wave, while frequency refers to the number of wave cycles in a given period of time. Changing the frequency of a wave will not alter its amplitude.


If AC means alternating current used to light up a bulb and alternating current moves up and down then why does light emitted from that bulb not alter to give us first a low light then a bright light?

Electric light bulbs use electric current to heat a filament to high temperature which produces electromagnetic radiation which appears to us as as "heat" in the invisible part of the frequency spectrum and "light" in the visible part. The alternating current (AC) voltage waveform changes at a frequency of 50 or 60Hz (cycles per second of a sine wave) depending on which country you live in. The filament stays heated from cycle to cycle of the AC voltage waveform - the highs and lows of the AC waveform are so close that the filament does not have time to cool off much. It thus seems to emit light continuously for us and we don't notice any reduction in light. One reason contributing to this is the persistence in vision of the human eye - we see anything happening at frame rate of 20 or more per second as continuous. If it were at a slower frequency of AC we would notice the changes in light intensity which occur at the different levels of voltage in the ac waveform.


How does mass affect pendulum frequency?

The frequency of a pendulum is not affected by its mass. The frequency is determined by the length of the pendulum and the acceleration due to gravity. A more massive pendulum will swing at the same frequency as a less massive one if they have the same length.


What happens to a wavelength when the amplitude and frequency are both increased?

When the amplitude and frequency of a wave are both increased, the wavelength remains constant. Amplitude affects the intensity or loudness of the wave, while frequency determines the pitch. Therefore, changing the amplitude and frequency does not alter the wavelength of the wave.
