Does intensity affect the wavelength?
Intensity does not affect wavelength. Wavelength is determined by the frequency of the wave and remains constant in a given medium regardless of the intensity of the wave. Intensity, on the other hand, is related to the amplitude of the wave, which determines the brightness or loudness of the wave.
When the amplitude decreases what happens to the frequency?
When the amplitude decreases, the frequency remains constant. Amplitude and frequency are independent of each other in a wave. The frequency determines the pitch of the sound or the color of light, while the amplitude determines the intensity or loudness of the sound or brightness of light.
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.
How are wavelength frequency intensity and energy related in an electromagnetic wave?
E = h f (relation of energy with frequency) E = h c / λ (relation of energy with wavelength) h = Planck's constant ≈ 6.026 × 10⁻³⁴ J.s c = speed of light = 299,792,458 m/s in vacuum ≈ 3.0 × 10⁸ m/s
What happens to the intensity of a wave if the amplitude decreases?
Intensity of a wave is proportional to the frequency squared and amplitude squared based on this formula; I=1/2pw^2A^2V where p is the density of the medium, w is the angular frequency and A is the amplitude and V is the wave velocity. So, everything else remaining constant, decreasing the amplitude will decrease a waves intensity. Example decreasing the the amplitude by a factor of 4 will decrease the wave intensity by a factor of 8.

In the Photoelectric effect after the threshold frequency what effect does the increased frequency have on the photocurrent If you assume the Intensity of the source to be constant?
The increased frequency increases the kinetic energy of the single electron ejected. Remember that the incident light releases a single electron when the threashod frequency is reached
Why transformer frequency is constant?
In transformer there is no rotating part.so frequency constant.

What factors frequency depends on?
The frequency depends on what the frequency is of. A pendulum or other simple harmonic motion has a constant frequency, a Poisson event has a variable frequency, although the long term average is a 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
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 could you tell whether a police car is chasing you or moving away from you from sound waves?
If the police car is chasing you, the sound waves will have a higher frequency and intensity as it approaches you. As the police car moves away, the sound waves will have a lower frequency and intensity. This change in frequency and intensity can help you determine whether the police car is getting closer or farther away.
How is intensity of a stimulus represented in an individual neuron?
The intensity of a stimulus is represented in an individual neuron by the frequency of action potentials it generates. A stronger stimulus leads to a higher rate of firing, while a weaker stimulus results in fewer action potentials. This phenomenon is known as frequency coding, where the information about stimulus intensity is encoded in the number of spikes per unit time. Additionally, the neuron may also exhibit adaptation, whereby its response decreases over time despite a constant stimulus intensity.
