Answer:

A=emitted B=absorbed

What is the solution to the problem to the correct number of significant figures (102,900/12)+(170•1.27)
GarryVolchara [31]

As per as the Multiplication rules of the significant figures, whenever any numbers in the decimals forms are multiplied or divided then result in mentioned in such a way so that the significant figures after the decimal will be same as that in the given least condition.


_______________________________


102900/12 = 8575


170 × 1.27 = 215.9


∴ (102,900 ÷ 12) + (170 × 1.27) =  8575 + 215.9


= 8790.9


Now, As per as Above rules, answer in correct significant figures will be = 8791.

What is the wavelength of radiation that has a frequency
White raven [17]

Answer:

\lambda = \frac{c}{\nu}

Explanation:

The wavelenght of  a radiation is inversely proportional to its frequency. It can be estimated by the following formula:

\lambda = \frac{c}{\nu}

Where:

  • \lambda is the wavelenght
  • \nu is the frequency
  • c is the speed of light (arroung 300000 km/s)
