A diffraction grating produces a first-order maximum at an angle of 10 degree. What is the angle of the third order maximum?

Physics
1 answer:
Ksenya-84 [330]4 years ago
3 0

Answer:

Explanation:

For first order maxima , the angle Φ

Φ in radian = 1.5 λ /a

For third order maxima , the angle in radian

= 3.5 λ / a  

Hence angle becomes 3.5/1.5 times in radian and therefore also in degree

Hence angle required is 10 x 3.5/1.5 degree or 23.33 degree.

Children slide down a friction-less water slide that ends at a height of 1.80 m above the pool. If a child starts from rest at p
Pachacha [2.7K]

Answer:

0.84 m

Explanation:

0.84 m

Explanation:

We are given that  

Height,h=1.80 m

Horizontal distance,L=2.43 m

We have to determine the height h of the water slide.

Initial velocity,u=0

t=\sqrt{\frac{2h}{g}}

Where g=9.8 m/s^2

t=\sqrt{\frac{2\times 1.8}{9.8}}=0.6 s

v=\frac{distance}{time}=\frac{2.43}{0.6}=4.05 m/s

h'=\frac{v^2}{2g}

h'=\frac{(4.05)^2}{2\times 9.8}

h'=0.84 m

Given the atomic radius of argon, 0.97 Å, and knowing that a sphere has a volume of 4πr3/3, calculate the fraction of space that
Bogdan [553]

Answer:

1.0x10^-4

Explanation:

First, in order to do this, we need to calculate the volume of 1 simple atom of Ar. Using the formula of the volume of a sphere we have the following

Converting A to cm:

0.97 * 1x10^-8 = 9.7x10^-9 cm

Now the volume:

V = 4/3π(9.7x10^-9)³

V = 3.82x10^-24 cm³

We know that 1 cm³ is 1 mL, and 1 L is 1000 mL so:

V = 3.82x10^-24 mL / 1000 = 3.82x10^-27 L

Now, using avogadro's number, we should get the total volume of all atoms of Ar so:

3.82x10^-27 * 6.02x10^23 = 2.3x10^-3 L

Finally, at STP the volume of an ideal gas is 22.4 L so:

2.3x10^-3 / 22.4 = 1.03x10^-4

With two significant figure, it would be 1.0x10^-4

A temperature measuring device should be placed in the __________ area of the refrigerated holding unit.
STatiana [176]
<span>A temperature measuring device should be placed in the "warmest" area of the refrigerated holding unit. The reason for this is because all foods must be stored in the minimum temperature required. If not stored properly the foods become hazardous. It is important to place the thermometer in the accurate location in reference to this question it is in the warmest location. The reasoning behind this is that if placed in the coldest location it may not represent an accurate temperature based on the entire unit.</span>
