Answer:
A. [tex]f=6.1475*10^{14}Hz[/tex]
B. [tex]f=5.9642*10^{14}Hz[/tex]
Explanation:
The frequency has an inversely proportional relationship with the concept of wavelength, the greater the wavelength, the lower the frequency. For electromagnetic waves, the frequency is equal to the speed of light, divided by the wavelength.
[tex]f=\frac{c}{\lambda}[/tex]
A.
[tex]f=\frac{3*10^8\frac{m}{s}}{488*10^{-9}m}\\\\f=6.1475*10^{14}Hz[/tex]
B.
[tex]f=\frac{3*10^8\frac{m}{s}}{503*10^{-9}m}\\\\f=5.9642*10^{14}Hz[/tex]
