Answer:

Step-by-step explanation:
The speed of light is
and its frequency is
.
The speed of light is given as:
c = λ * f
where λ = wavelength of light
f = frequency of light
Therefore, the wavelength is given as:
λ = c / f
=> λ = 
=> λ = 
The wavelength of the light is 
Part A
25-9=16
16/2=
8
The length of the rope holding the top right corner of the banner to the post is
8 feet long
Part B
13-9-2=
2 for width
25-8=16 16/2=
8 for length
Use the Pythagorean Theorem

+

=


64+4=

68=


34=c
The length of the rope from the bottom right corner of the banner to the post is
34 feet
