Questions & Step-by-Step Solutions

What is the wavelength of light with a frequency of 5 x 10^14 Hz? (Speed of light = 3 x 10^8 m/s)
  • Step 1: Identify the formula to calculate wavelength (λ). The formula is λ = c / f, where c is the speed of light and f is the frequency.
  • Step 2: Write down the values you have. The speed of light (c) is 3 x 10^8 m/s and the frequency (f) is 5 x 10^14 Hz.
  • Step 3: Substitute the values into the formula. So, λ = (3 x 10^8 m/s) / (5 x 10^14 Hz).
  • Step 4: Perform the division. Calculate 3 x 10^8 divided by 5 x 10^14.
  • Step 5: Simplify the calculation. This gives you λ = 0.6 x 10^-6 m.
  • Step 6: Convert the result into micrometers (µm). Since 1 µm = 10^-6 m, λ = 0.6 µm.
