We don't know what "the following" are, and we don't know
which kinds of atoms you have in mind. Other than that, this
could be an intriguing question.

A thin oil slick (no=1.50) floats on water (nw=1.33). When a beam of white light strikes this film at normal incidence from air,

Sedbober [7]

Answer:

The (minimum) thickness of the oil slick is 325 nm.

Explanation:

Let the (minimum) thickness of the oil slick = $t_{o}$

Therefore:

2 $t_{o}$ = ( $m_{red}$ + $\frac{1}{2}$ )*λ $_{red}$ / $n_{o}$ (1)

similarly,

2 $t_{o}$ =( $m_{violet}+\frac{1}{2}$ )*λ $_{violet}$ / $n_{o}$ (2)

Thus, equation 1 = equation 2

( $m_{red}$ + $\frac{1}{2})$ *λ $_{red} /n_{o}$ = ( $m_{violet}+\frac{1}{2})$ *λ $_{violet}/n_{o}$

Where:

λ $_{red} = 650 nm$

λ $_{violet} = 390 nm$

$n_{o} = 1.5$

Therefore:

$\frac{2m_{violet}+1 }{2n_{red}+1 }$ =650/390=5/3

This shows that,

$m_{violet}$ =2

$m_{red}$ =1

Thus, using equation 2

$t_{o}$ = $\frac{5*390}{2*2*1.5} =325 nm$

A marble dropped in still water will create circular ripples or waves. the radius of each circular wave will increase 4 centimet

Gnom [1K]

The circumference of the circle after t seconds = 25.12 t

Given data,

The radius of each circular wave will increase by four centimeters per second (cm/s)

In 1 second of circular wave radius = 4cm

In 1*t second of circular wave radius = 4t cm

As a result, the radius of the circular wave after t seconds is 4t cm.

We already know that the circumference of a circle is given by = 2πr, where r is the circle's radius.

As a result, the radius of a circular wave after t seconds is = 2π * radius of a circular wave after t seconds = 2π * 4t

= 8πt

( Taking π = 3.14 )

As a result, the circumference of the circle after t seconds = 8πt

= 3.14t

= 25.12t

A 0.600 m long pendulum is used to determine the acceleration due to gravity on a distant planet. If 20 complete oscillation are

givi [52]

Answer :

Explanation :

It is given that,

length of pendulum, l = 0.6 m

Number of oscillation, n = 20

time, t = 35.5 seconds

so, Time period, $T=\dfrac{t}{n}$

$T=\dfrac{35.5s}{20}$

we know that the time period of pendulum is given by

$T=2\pi\sqrt{\dfrac{l}{g}}$

$g=\dfrac{4\pi^2l}{T^2}$

$g=\dfrac{4\times(3.14)^2\times 0.6 \times (20)^2}{(35.5s)^2}$

$g=7.51\ m/s^2$

$g=7.52\ m/s^2$
