Answer:
2.92682 m
[tex]1.5\times 10^{18}\ Hz[/tex]
250000000000 Hz
[tex]2.88462\times 10^{-8}\ m[/tex]
0.21126 m
0.12244 m
Explanation:
c = Speed of light = [tex]3\times 10^8\ m/s[/tex]
[tex]\lambda[/tex] = Wavelength
f = Frequency
Wavelength is given by
[tex]\lambda=\dfrac{c}{f}\\\Rightarrow \lambda=\dfrac{3\times 10^8}{102.5\times 10^6}\\\Rightarrow \lambda=2.92682\ m[/tex]
The wavelength is 2.92682 m
Frequency is given by
[tex]f=\dfrac{c}{\lambda}\\\Rightarrow f=\dfrac{3\times 10^8}{0.2\times 10^{-9}}\\\Rightarrow f=1.5\times 10^{18}\ Hz[/tex]
The frequency is [tex]1.5\times 10^{18}\ Hz[/tex]
[tex]f=\dfrac{c}{\lambda}\\\Rightarrow f=\dfrac{3\times 10^8}{1.2\times 10^{-3}}\\\Rightarrow f=250000000000\ Hz[/tex]
The frequency is 250000000000 Hz
[tex]\lambda=\dfrac{c}{f}\\\Rightarrow \lambda=\dfrac{3\times 10^8}{1.04\times 10^{16}}\\\Rightarrow \lambda=2.88462\times 10^{-8}\ m[/tex]
The wavelength is [tex]2.88462\times 10^{-8}\ m[/tex]
[tex]\lambda=\dfrac{c}{f}\\\Rightarrow \lambda=\dfrac{3\times 10^8}{1.42\times 10^{9}}\\\Rightarrow \lambda=0.21126\ m[/tex]
The wavelength is 0.21126 m
[tex]\lambda=\dfrac{c}{f}\\\Rightarrow \lambda=\dfrac{3\times 10^8}{2.45\times 10^9}\\\Rightarrow \lambda=0.12244\ m[/tex]
The wavelength is 0.12244 m
