-What is the wavelength of a 2.28 x 1017 Hz wave?
1 answer:
I attached the working and the answer to both questions below.
Please note that C = speed of light, ν = frequency, λ= wavelength
<span>The wavelength of a 2.28 x 10</span>¹⁷<span> Hz wave is 1.31 </span>×<span> 10</span>⁷ cm<span>
The frequency of a 7.30 x 10</span>⁻⁵<span> m wave 4.11 </span>×<span> 10</span>¹² s⁻¹
Please note that C = speed of light, ν = frequency, λ= wavelength
<span>The wavelength of a 2.28 x 10</span>¹⁷<span> Hz wave is 1.31 </span>×<span> 10</span>⁷ cm<span>
The frequency of a 7.30 x 10</span>⁻⁵<span> m wave 4.11 </span>×<span> 10</span>¹² s⁻¹

Answer:
36 loaves of bread and 18.48 ounces of mayonnaise are needed to make all of the sandwiches.
Explanation:
Number of slices of ham = 231
Given that each sandwich has 1 slice of ham.
Then 231 slices of ham will be in :
A single sandwich is made up of 2 bread slices , Then bread slices in 231 sandwiches will be :
Each bread slice is applied with 0.0500 ounce of mayonnaise.
Then 462 bread slices will have :
1 bread loaf = 13 bread slices
Then breads loves in 462 bread slices :
36 loaves of bread and 18.48 ounces of mayonnaise are needed to make all of the sandwiches.
