Problem 9) If you had light of wavelength 700nm when emitted, what would the wavelength be for an observer who is a red shift z = 0.05 from that source?

The answer is 735 Nanometer

Explanation:

Solution to this problem

Given that:

Solution)

The Redshift is categorized by the  difference related between  wavelength(emitted)  and wavelength (observer).

Now,

The wavelength can be computed as  :

1+z=\lambda (observer)\div \lambda (emitted)

hence,

1 + 0.05 = λ(observer) / 700 nm

Gives

= 1.05*700  = 735 nm

Therefore, The wavelength from that source for an observer would be 735 nanometer

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
