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

Answer:

Heyy mate!! Here is your answer

Step-by-step explanation:

TanA = Cot B

TanA = Tan (90-B) . • CotB = Tan (90-B)

cancelled Tan from both sides Then,

A= 90-B

A+B =90

Proved
