An application of this principle is that a line mounted on transparent slide casts the same diffraction pattern as a dark film with a slot of equal size cut in it. in part 6.2.5 of the experiment, you will exploit this principle to measure the width of a hair. if the distance between the first spot and the central minimum is s = 0.7 cm, l = 12 m, and λ = 6 x 1 0 ^− 7 , what is the width of the hair (mm)?

Explanation:

It is given that,

The distance between the first spot and the central minimum is, s = 0.007 cm

Length, l = 12 m

Wavelength,

We need to find the width of the hair. Using the condition of diffraction pattern as :

, d is the width of the hair

d = 0.00102

or

So, the width of the hair is . Hence, this is the required solution.

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.
