What is the energy of a photon that has a wavelength corresponding to the peak in the figure? Planck's constant is h=6.626*10^ -34 J•s and the speed of light is c=3.00*10^ 8 m/s . This graph represents the intensity of light as a function of wavelength (λ) in nanometers (nm). The x-axis denotes the wavelength ranging from 700 nm to 1100 nm, while the y-axis represents the intensity on a scale of 0 to 1.### Key Observations:- **Peak Intensity**: The graph shows a sharp peak at around 950 nm, indicating maximum intensity at this wavelength.- **Symmetry**: The curve is approximately symmetrical around the peak.- **Width**: The intensity rapidly increases before 950 nm and decreases after, suggesting a narrow wavelength range with high intensity.This type of graph is commonly used to illustrate emission spectra, where specific wavelengths correspond to the emission lines of a particular light source. The shape and position of the peak can provide valuable information about the material or conditions generating the spectrum.

The expression for the energy of photon is shown below:E = hcλ where; E =energy of photon h = Planck's constant c = speed of light λ = wavelengthGiven information: wavelength = 950 nm = 9.50 ×10-7 m Planck's constant = 6.626×10-34 Js speed of light = 3×108 ms-1The calculation of energy is shown below: E = hcλ= 6.626 ×10-34 ×3×1089.50×10-7= 2.09 ×10-19 J= 2.09 ×10-22 kJAnswer: energy of photon is 2.09×10-22 kJ
