Perhaps to confuse a predator, some tropical gyrinid beetles(whirligig beetles) are colored by optical interference that is duet
gulaghasi [49]

Answer:

The grating spacing of the beetle is 1.078*10^{-6}m

Explanation:

The concept to solve this problem is relate to interference effect given in the Young's Slits. Here was demonstrated that the length of the side labelled \lambda is known as the path difference. The equation is given by,

n\lambda = dsin\theta

Where,

\lambda= wavelenght of light

N = a positive integer: 1,2,3...

\theta = Angle from the center of the wall to the dark spot

d= width of the slit

Replacing our values we have that for n=1,

dsin\theta = n\lambda

dsin(30)=(1)(539*10^{-9})

d=1.078*10^{-6}m

Therefore the grating spacing of the beetle is 1.078*10^{-6}m

Derive a relation between Universal Gravitational Constant (G) and Acceleration due to gravity(g)?
snow_tiger [21]
Suppose earth is a soid sphere which will attract the body towards its centre.So, acc. to law of gravitation force on the body will be,
F=G*m1m2/R^2
but we now that F=ma
and here accleration(a)=accleration due to gravity(g),so
force applied by earth on will also be mg
replace above F in formula by mg and solve,
F=G*mE*m/R^2                             ( here mE is mass of earth and m is mass of body)
mg=G*mEm/R^2
so,
g =G*mE/R^2
