Ahe–ne laser illuminates a narrow, single slit that is 1850 nm wide. the first dark fringe is found at an angle of 20.0∘ from the central peak. 1) determine the wavelength of the light from the laser. (express your answer to three significant figures.)

Wavelength of light will be 632.73 nm

Explanation:

We have given width of the single slit

Angle is given as

We have to find the wavelength of light for first dark fringe

We know that for dark fringe it is given that

For first fringe n = 1

So

i think its

hi there!

your question asks at which segment does freezing occur.

since we're talking about water, the freezing point of water will be 32 degrees fahrenheit or below.

hope this ! ~
