Question

the rydberg constant is 3.3 x 10^15 hz. this value is also
the frequency of light emitted by our sun.
the ionization frequency of iron.
the average frequency of electromagnetic radiation.
the ionization frequency of hydrogen.

question 2
1 pts
what is the frequency of light released when an electron moves from the 2nd energy level to the 1st energy level in hydrogen (dont reach for a calculator, you should be able to estimate 3/4s of a number like 3.3).
2.5 x 10^12 hz
3.3 x 10^18 hz
3.3 x 10^14 hz
2.5 x 10^15 hz

question 3
1 pts
in a hydrogen atom which transition would emit the longest wavelength of light?
n=2 to n=1
n=4 to n=1
n=3 to n=1
n=6 to n=5

Explanation:

Step1: Recall Rydberg constant property

The Rydberg constant is related to the ionization frequency of hydrogen.

Step2: Analyze Question 2

Estimate 3/4 of 3.3. 3.3×3/4 = 2.475≈2.5, and for hydrogen electron transition from n = 2 to n = 1, the frequency is on the order of 10^15 Hz.

Step3: Analyze Question 3

Use the formula E=h*c/λ. Smaller energy difference gives longer - wavelength. The transition from n = 6 to n = 5 has the smallest energy difference among the given options.

Answer:

Question 1: the ionization frequency of hydrogen
Question 2: 2.5 x 10^15 Hz
Question 3: n=6 to n=5
