1. Light of wavelength 900x10-9 m is emitted by a source. What is its frequency?
Answers
therefore the frequency = 6×10^14
The frequency of the light is "[tex]6\times 10^{14}[/tex]".
Given values:
Wavelength,
[tex]\lambda = 900\times 10^{-9} \ m[/tex]
As we know the formula,
→ [tex]Frequency = \frac{C}{\lambda}[/tex]
By substituting the values, we get
→ [tex]= \frac{3\times 10^8}{900\times 10^{-9}}[/tex]
→ [tex]= \frac{10^8}{300\times 10^{-9}}[/tex]
→ [tex]= 6\times 10^{14}[/tex]
Thus the above response is correct.

A loan of $12000 was borrowed from the bank at 14% per annum calculate the interest on the loan at the end of the first year ?
Answers
Answer:
lmasjsjsjssjjssjjssjsjjsksakkalaaooaa
Loan borrowed = $12,000
Percentage of interest on the loan per annum = 14%
We know that :
[tex]\color{hotpink}\tt \: Simple \: interest = \color{plum}\frac{principal \times rate \times time}{100} [/tex]
In this case :
principal = $12000rate = 14%time = 1 yearSimple interest at the end of the first year :
[tex] = \tt \frac{12000 \times 14 \times 1}{100} [/tex]
[tex] = \tt \frac{168000}{100} [/tex]
[tex]\color{plum}\tt = \$1680[/tex]
Thus, interest = $1680
Therefore, total interest on the loan at the end of one year = $1680
