- quantum mechanics Question3) Electrons are filled in various sub-shells from higher energy to lower energy. Select one: True FalseQuestion states. Select all forms that would definitely produce the photoelectric effect from a piece of metal if you know that visible light produces the photoelectric effect from this metal.
- QUESTION 3 What is the the frequency (in kHz) of gamma ray radiation that has a wavelength of 0.01516 nanometers? The speed of light is 3.00x10 8 m/s. Key Concept: Frequency, ν, and wavelength, λ, of light are inversely related to each other by c = λ*ν where c is the speed of light.In the lab manual five different named series of lines are given. Create a table that lists the named series, the ending level; the type of electromagnetic emission given off (UV, Visible…) and whether they would be visible to the human eye.What is the relationship between wavelength and frequency? As wavelength increases frequency increases As wavelength increases frequency decreases As wavelength increases frequency remains the same No relationship
- For any wave, the speed equals the wavelength times the frequency. If a photon of visible light has a wavelength of 500 nm (5 x 10-7 m) and a frequency of 6.0 x 1014 Hz, what is the speed of light (in meters per second, scientific notation)?TYPE ALL WORK OUT PLEASE and USE CORRECT Sig Figs!!! Question 8 A microwave is found to emit electromagnetic radiation with a frequency of 378 MHz. Determine the energy (in J) of a photon from this microwave. For large numbers, you can leave off the "x 10" portion here. For example, if you answer is 5.5 x 1025, you can type "5.5" here and write the full answer on your paper.The energy for one state of the H atom is -5.45 × 10 -19 J. What frequency (Hz) of light would need to be absorbed to reach a state with an energy of -8.72 × 10 -20 J? Express answer in scientific notation.
