Calculate the wavelength, in nanometers, of the following wave frequencies:
- a. 6.79 × 1014 s−1
- b. 4.44 × 1012 Hz
(a)
Interpretation:
Using the given frequency value, the wavelength in nanometers has to be calculated.
Concept-Introduction:
Wavelength: The distance between successive peaks in a wave and measured in units of length.
Frequency: The number of waves passed a point in a certain amount of time.
Relation between wavelength and frequency:
Where, c is constant, the value of c is
Explanation of Solution
Given: Frequency
Using the relation
Therefore, the wavelength in nanometer is
(b)
