In an experiment, technicians measure 11 bright fringes on a wall 2.0 m away from a double slit screen that has a spacing between the slits of 120 μm. if the distance from end to end of these 11 bright fringes is 8.5 cm, what is the wavelength of light?

No

Step-by-step explanation: The set of counting numbers {1, 2, 3, 4, ...} is called the set of natural numbers. The natural numbers begin with 1 and go on indefinitely.

Decimals are not natural numbers unless they have a 0 after the decimal point that repeats. However, 2.8 does not so it's not natural.
