Questions & Step-by-Step Solutions

What is the wavelength of light with a frequency of 5 x 10^14 Hz?
  • Step 1: Understand the formula for wavelength (λ). The formula is λ = c / f, where c is the speed of light and f is the frequency.
  • Step 2: Identify the values needed. The speed of light (c) is 3 x 10^8 meters per second (m/s) and the frequency (f) is given as 5 x 10^14 Hertz (Hz).
  • Step 3: Substitute the values into the formula. Replace c with 3 x 10^8 and f with 5 x 10^14 in the formula: λ = (3 x 10^8) / (5 x 10^14).
  • 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 meters.
  • Step 6: Convert to standard scientific notation. 0.6 x 10^-6 can be written as 6 x 10^-7 meters.
