It makes sense that intensity of light affects the photoelectric current, but what about the frequency and wavelength, given that intensity remains constant? The formula for intensity would be I = nhf/tA (where n is the number of photons and hf the energy of one pho...
In summary, if a wave of velocity v, frequency f and wavelength \lambda travels through a medium, the further the wave travels the greater the velocity of wave. However, if either the wavelength or the frequency is held constant and the wave speed increases, how do the...
a• Like the three LEDs, the buzzer guides you to the target torque (or angle); it increases the frequency of its signals as torque (or angle) increases, and emits a different signal if the torque (or angle) goes over the maximum value. • 象三LEDs,蜂音器引导您到目标扭矩 (或...
- As the temperature T increases, the velocity v of sound will also increase. 2. Identify the Parameters to Analyze: - The parameters given in the question are displacement, amplitude, frequency, wavelength, and time period. We need to determine which of these will change with an increase in...
