WebOct 21, 2024 · The fertilized egg is an indispensable production platform for making egg-based vaccines. This study was divided into two parts. In the first part, image processing was employed to analyze the absorption spectrum of fertilized eggs; the results show that the 580-nm band had the most significant change. In the second part, a 590-nm … WebIn an experiment tungsten cathode which has a threshold wavelength 2300Å is irradiated by ultraviolet light of wavelength 1800Å. Calculate. i. Maximum energy of emitted photoelectrons and ii. Work function of tungsten. (Mention both the result in electron-volts) Given Planck ... 0 = 2300Å = 2300 10-10 m, ...
