Question

calculate the wave number of the radiations having frequency of 4×10¹⁴Hz.​

Answer 1

Answer:

4/3×10⁶

Explanation:

frequency=speed of light/wavelength.

we know, 1/wavelength=wave number.

Therefore, frequency=speed of light× wave number.

According to question,

4×10¹⁴=3×10⁸×wave number

wave number=(4×10¹⁴)/(3×10⁸)=4/3×10⁶.
