Significant digits are the number of digits that reflect the precision of a measurement or number.
Delvig [45]

Answer:

True

Explanation:

Significant digits are numbers that helps to present the precision of measurements calculations.

Numbers that do not contribute to the precision of a reading should not be counted as significant.

There are rules of assigning significant numbers:

  • Leading or trailing zeros are insignificant and should only be counted as a place holder.
  • All non-zero digits are significant
  • Zeroes between non-zero digits are significant.
  • Leading zeros in a decimal are significant before the number.
  • All the numbers in a scientific notation are significant.

What is the frequency of green light that has a wavelength of 5.14 x 10^-7m?
nata0808 [166]

Answer:

Frecuency = 5,83x10⁻⁷ Hz

Explanation:

The equation that connects wavelenght and frequency is given by:

λ = c/ν

λ=wavelenght (expressed in lenght´s units)

c= speed of light (3x10⁸ m/sec)

ν=frequency (expressed in units of time⁻¹ or Herzt)

In our case, λ=5,14x10⁻⁷ m , so replacing in our previous formula, this gives us the final result of ν (frequency for green light) of 5,83x10¹⁴ Hz (or Herzt)
