Question

If the distance between the first bright band and the tenth bright band in Yeong He's slits experiment is (18 mm) and the distance between the two parallel slits is (0.15 mm) and the screen is (0.5 m) away from the barrier, what is the frequency of the light used?

Answer 1

The wavelength of light used in Yeong He's slits experiment can be calculated using the formula: wavelength = (distance between bright bands) x (distance between screen and slits) / (distance between slits).

Step-by-step explanation:

In Young's double-slit experiment, the distance between the slits (d) can be calculated using the formula:

d = (distance between bright bands) x (wavelength) / (distance between screen and slits)

Using the given values, we can rearrange the formula to find the wavelength of light used:

wavelength = (distance between bright bands) x (distance between screen and slits) / (distance between slits)

Substituting in the given values, we find that the wavelength of light used is 0.15 mm x 0.5 m / 18 mm = 0.0083333 m (rounded to 7 decimal places).
