Final answer:
The correct answer is option 4: Yellow, 2 x 10^6 Hz.
Step-by-step explanation:
The wavelength of light is inversely proportional to its frequency. According to the information given, the approximate frequency of the light is represented by Option 4: Yellow, 2 x 10^6 Hz. Therefore, the corresponding wavelength of this light can be calculated using the equation:
wavelength = speed of light / frequency
wavelength = 3 x 10^8 m/s / (2 x 10^6 Hz) = 150 m
To calculate the approximate energy of one photon of this light, we can use the equation:
energy = Planck's constant x frequency
energy = 6.626 x 10^-34 J s x (2 x 10^6 Hz) = 1.3252 x 10^-27 J
Therefore, the approximate energy of one photon of yellow light with a frequency of 2 x 10^6 Hz is 1.3252 x 10^-27 J.
