Light waves are traveling through glass. If the wavelength of some part of the light wave is 4 x 10-7 m and the frequency of that light is 5 x 1014 Hz, what is the speed of light through the glass?
speed is measured in m/s, so it is clear that
v = (4*10^-7m)*(5*10^14/s) = 2*10^8 m/s
thank you
To find the speed of light through the glass, we can use the formula:
Speed = Wavelength x Frequency
Given:
Wavelength = 4 x 10^(-7) m
Frequency = 5 x 10^(14) Hz
Plug in the values into the formula:
Speed = (4 x 10^(-7)) x (5 x 10^(14))
Now, let's simplify this expression:
Speed = 20 x 10^(7)
To simplify further, we can convert 20 x 10^(7) into scientific notation:
Speed = 2 x 10^(8) m/s
Therefore, the speed of light through the glass is 2 x 10^(8) m/s.
