You illuminate a slit with a width of 70.3 μm with a light of wavelength 719 nm and observe the resulting diffraction pattern on

Zielflug [23.3K]

Answer:

4.3 cm

Explanation:

We are given that

Width,d=70.3 $\mu m=70.3\times10^{-6} m$

$1\mu m=10^{-6} m$

Wavelength, $\lambda=719 nm=719\times 10^{-9} m$

$1nm=10^{-9} m$

$r=2.11 m$

We have to find the width in cm of the pattern.

The angle for the first minimum m=1

$sin\theta_{min}\approx \theta=\frac{\lambda}{d}=\frac{719\times 10^{-9}}{70.3\times 10^{-6}}=0.0102 rad$

$y=r\theta=2.11\times 0.0102=0.0215 m$

The width of the pattern= $2y=2\times 0.0215=0.043 m=0.043\times 100=4.3 cm$

Acceleration on moon is approximately 1/6th of the Earth's; what would be the force of your egg drop package if dropped on the m

cricket20 [7]

Acceleration on earth=10m/s^2

Acceleration on moon:-

$\\ \rm\Rrightarrow 10\dfrac{1}{6}=1.6m/s^2$

Now

Mass=0.56kg

$\\ \rm\Rrightarrow F=ma$

$\\ \rm\Rrightarrow F=0.56(1.6)$

$\\ \rm\Rrightarrow F=0.896N$
