Suppose i create a two-slit interference pattern using light with some wavelength lambda and slits with some separation d. if i were to increase lambda, what would happen to the interference pattern on the wall? the pattern would spread out nothing would happen to the pattern the pattern would compress

The pattern would spread out.

Explanation:

The fringe  width is given by the relation

fringe width = λ L / D where λ is wavelength of light used, L is distance of wall from the source of light and D is slit separation.

If we increase λ , fringe width will increase and therefore pattern will spread out .

emily ruth's annual premium is $1058.50

step-by-step explanation:

emily ruth is a female of 27 years age purchasing 20 year endowment insurance with face value $25000.

from the given table,

for females, the age of a male 3 years younger should be used.

so, we have to check for 24 year male for 20 year endowment.

it is 42.34 for every $1000 face value.

for a face value of $25000,

it is 25 * 42.34 = $1058.50

∴ emily ruth's annual premium is $1058.50

real, smaller and upside-down.   so the answer should be b.
