Calculate the wavelength in meters corresponding to electromagnetic radiation with a frequency of 7.94×1017 Use c=2.998×1017 m/s

For an advanced lab project, you are studying an unknown hydrogen-like atom. For these atoms, you determine that as excited atoms de-excite, the n = 3 → 2 transition emits a wavelength of 2.624 ✕ 10−8 m and the n = 4 → 2 transition emits a wavelength of 1.944 ✕ 10−8 m. Determine the wavelength (in m) of light emitted in the n = 4 → 3 transition. _______ m

The work function (φ) for a metal is the amount of energy needed to eject an electron from the surface of the metal via the photoelectric effect. For nickel φ = 8.25 x 10-19J. Will a photon with a wavelength (λ) of 250.0 nm have enough energy to eject an electron from nickel?  If the speed of an electron in the n = 4 energy level of a hydrogen electron is 2.3 x 106 m/s, what is the de Broglie wavelength of this electron in nanometers (the mass of an electron is 9.10938 x 10-31 kg). Note: 1 ? = 1 ?? ∙?2 An F-15 Strike Eagle weighs in at roughly 32,000 kg fully loaded. If an F-15 Eagle is traveling at 3,017 kilometers per hour, what is the de Broglie wavelength associated with the aircraft at this speed in nanometers?
