Final answer:
The statement is true; the Rydberg constant is correctly given as 1.0974 x 10⁷ m⁻¹ and is used in the Rydberg formula to calculate the wavelengths of emitted electromagnetic radiation in spectral emissions. The correct option is (A) True.
Step-by-step explanation:
The statement is true; the Rydberg constant has a value of 1.0974 x 10⁷ m⁻¹. This constant is used in the Rydberg formula to calculate the wavelengths of the emitted electromagnetic radiation in spectral line emissions of hydrogen and other elements.
The formula generally looks like this: 1/λ = R (1/n1² - 1/n2²), where λ is the wavelength of the emitted radiation, n1 and n2 are positive integers with n2 > n1, and R represents the Rydberg constant.
To summarize, the Rydberg constant is a physical constant that appears in the formulas describing the wavelengths of spectral lines of hydrogen and hydrogen-like ions. It is named after the Swedish physicist Johannes Rydberg.
