What is the wavelength of radiation whose frequency is 1.56 x 10^12 Hertz?

1.92×10¯⁴ m

Explanation:

From the question given above, the following data were obtained:

Frequency (f) = 1.56×10¹² Hz

Wavelength (λ) =?

Frequency and wavelength of a wave are related by the following equation:

v = λf

Where

'v' is the velocity of light with a constant value of 3×10⁸ m/s.

'λ' is the wavelength

'f' is the frequency.

Thus, we can obtain the wavelength of radiation by using the above formula as illustrated below:

Frequency (f) = 1.56×10¹² Hz

Velocity (v) = 3×10⁸ m/s.

Wavelength (λ) =?

v = λf

3×10⁸ = λ × 1.56×10¹²

Divide both side by 1.56×10¹²

λ = 3×10⁸ / 1.56×10¹²

λ = 1.92×10¯⁴ m

Therefore, the wavelength of the radiation is 1.92×10¯⁴ m

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml
