Referring to Example 31–3 (a) Which state has a de Broglie wavelength of 3.99 × 10−9 m? (b) What is the Bohr radius of this state?

Solution 92IP

Step 1 of 3</p>

Here, we have to calculate the state and the Bohr radius.

The radius of the nth orbit is,

Where - state

- Radius of the 1st Bohr orbit

a)

Step 2 of 3</p>

The equation for the wavelength is,

Where, - Circumference of the orbit or the length which the standing wave travels

Or,

Or,

Therefore,

Provided,

We know that,

Therefore,
