Number of Spectral Lines Solution

Follow our step by step solution on how to calculate Number of Spectral Lines?

FIRST Step Consider the formula

n s = \frac{n quantum \cdot (n quantum - 1)}{2}

Next Step Substitute values of Variables

∴

n s = \frac{8 \cdot (8 - 1)}{2}

Next Step Prepare to Evaluate

∴

n s = \frac{8 \cdot (8 - 1)}{2}

LAST Step Evaluate

∴

n s = 28
