​

Answer 1

Answer:

Wave Number Definition

Step-by-step explanation:

In physics, the wave number is also known as propagation number or angular wave number is defined as the number of wavelengths per unit distance the spacial wave frequency and is known as spatial frequency.

Answer 2

Given :-

• The sum of 12 observations = 240 .

To Find :-

• Find the mean ?

Solution :-

we know that,

• Mean = (sum of observation) / (number of observation)

we have given that,

• sum of observations = 240 .
• Number of observations = 12

so,

→ Mean = 240 / 12

→ Mean = 20 (Ans.)

Hence, Mean of observations is 20.
