Use the Rydberg Equation 1/λ = R(1/n²(final) - 1/n²(initial) where R = 109,678 cm⁻¹. Substitute initial orbital number and final orbital number and solve for wavelength (λ).
Explanation:
Example:
Assume an electron transition from n = 5 to n = 2.
What causes the seasons? The seasons are caused by the tilt of the Earth's rotational axis away or toward the sun as it travels through its year-long path around the sun.
Statement 2 is correct. solids moving into solution is a physical change as the core structure of the molecules remain the same. evaporation of water and crystallization of salt are both physical changes as well. The water does not change it's H2O chemical makeup because salt was dissolved into it.
