Answer 1

1.09 * 10^-2

Step-by-step explanation:

I got it right when I did it. This is the right answer. I tried the other answer and was wrong that the other guy posted.

Answer 2

0.011 m

Step-by-step explanation:

From the question,

The speed of a moving wave is related as

c = λf.................... Equation 1

Where c = speed of the wave, λ = wave length, f = frequency.

make λ the subject of equation in equation 1 above

λ = c/f................ Equation 2

Given: c = 3.0×10⁸ m/s, f = 2.75×10¹⁰ Hz

Substitute theses values into equation 2

λ = 3.0×10⁸/(2.75×10¹⁰)

λ =
