An argon ion laser emits light of wavelength of 488 nm. (a) Calculate the frequency of the light. (b) Suppose a pulse of light f
Alex787 [66]

Answer:

A) 6.15×10^14 per sec

B)2.5 sec

Explanation:

Wavelength of light = 488 nm

speed of light = 3×10^8 m/s

therefore, frequency of light  \nu=\frac{c}{\lambda}

⇒ \nu=\frac{3\times10^8}{488\times10^{-9}}

⇒ν= 6.15×10^14 per sec

b) distance between moon and earth =  3.8×10^5 km.

= 3.8×10^8 m

light travel from earth moon and back to earth

therefore, distance traveled= 2× 3.8×10^8 m = 7.6×10^8 m

therefore time= distance/speed

⇒ time= \frac{7.6\times10^8}{3\times10^8}

= 2.5 sec

So, for a round trip time required is 2.5 sec.

Chlorine has two isotopes, 35Cl and 37Cl that have the respective percent abundance's of 75.77% and 24.23% and masses of 34.9688
AnnyKZ [126]

Answer:

The answer to your question is  35.4527 g

Explanation:

Data

Cl-35    abundance = 75.77 %    mass Cl-35 = 34.9688

Cl-37     abundance = 24.23 %   mass Cl-37 = 36.9659

Process

1.- Convert the percents to decimals

   75.77% = 75.77/100 = 0.7577

   24.23% = 24.23/100 = 0.2423

2.- Find the atomic weight

    Average atomic weight = Abundance 1 x Mass Cl-35 +

                                               Abundance 2 x Mass Cl-37

Substitution

     Average atomic weight = (0.7577)(34.9688) + (0.2423 x 36.9659)

Simplification

     Average atomic weight = 26.4959 + 8.9568

Result

      Average atomic weight = 35.4527 g
