Aphysics instructor wants to produce a double-slit interference pattern large enough for her class to see. for the size of the room, she decides that the distance between successive bright fringes on the screen should be at least 3.00 cm. if the slits have a separation d=0.0175mm, what is the minimum distance from the slits to the screen when 632.8-nm light from a he-ne laser is used?

0.83 m

Explanation:

w = distance between successive bright fringes = 3.00 cm = 0.03 m

d = separation between the slits = 0.0175 mm = 0.0175 x 10⁻³ m

λ = Wavelength of the light from He-Ne laser = 632.8 x 10⁻⁹ m

D = distance of the screen from the slits  = ?

Distance between successive bright fringes is given as

Inserting the values

D = 0.83 m

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper.

hi,

what occurs during a solar eclipse?

there are small tides across earth.

the moon is between earth and the sun.

p.s. im not sure if the first answer is correct because during a solar ecliphse there are spring tides and i dont know if they are the same.
