More than doubled.
The stopping voltage is the photon energy minus the work function:
hv - W
Doubling the photon energy creates a new stopping voltage of:
2 hv - W > 2 (hv - W)
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, 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.
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.
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
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.

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

In transformer there is no rotating part.so frequency constant.

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.
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
frequency = speed of wave / wavelength so if speed is constant then frequency varies inversely with wavelength
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.
The frequency in Planck's equation refers to the frequency of electromagnetic radiation, such as light. The equation relates the energy of a photon to its frequency through the constant known as Planck's constant.
