Answer:
4.74×10¹⁴ Hz.
Explanation:
From the question given above, the following data were obtained:
Wavelength of light = 633 nm.
Frequency of light =?
Next, we shall convert 633 nm to metre (m)
This can be obtained as follow:
1×10⁹ nm = 1 m
Therefore,
633 nm = 633 nm × 1 m / 1×10⁹ nm
633 nm = 6.33×10¯⁷ m
Thus, 633 nm is equivalent to 6.33×10¯⁷ m
Finally, we shall determine the frequency of the light as follow:
Wavelength of light = 6.33×10¯⁷ m
Velocity of light = 3×10⁸ m/s
Frequency of light =?
Velocity = wavelength x frequency
3×10⁸ = 6.33×10¯⁷ x frequency
Divide both side by 6.33×10¯⁷
Frequency = 3×10⁸ / 6.33×10¯⁷
Frequency = 4.74×10¹⁴ Hz.
Therefore, the frequency of the light is 4.74×10¹⁴ Hz.
