In a Young's double-slit experiment, a set of parallel slits with a separation of 0.102 mm is illuminated by light having a wave

guajiro [1.7K]

Answer:

Rounded to three significant figures:

(a) $2 \times 575\; \rm nm = 1150\; \rm nm = 1.15\times 10^{-6}\; \rm m$ .

(b) $\displaystyle \left(1 + \frac{1}{2}\right) \times (575\;\rm nm) \approx 863\; \rm nm = 8.63\times 10^{-7}\; \rm m$ .

Explanation:

Consider a double-slit experiment where a wide beam of monochromatic light arrives at a filter with a double slit. On the other side of the filter, the two slits will appear like two point light sources that are in phase with each other. For each point on the screen, "path" refers to the length of the segment joining that point and each of the two slits. "Path difference" will thus refer to the difference between these two lengths.

Let $k$ denote a natural number ( $k \in \left\lbrace0,\, 1,\, 2,\, \dots\right\rbrace$ .) In a double-split experiment of a monochromatic light:

A maximum (a bright fringe) is produced when light from the two slits arrive while they were in-phase. That happens when the path difference is an integer multiple of wavelength. That is: $\text{Path difference} = k\, \lambda$ .

Similarly, a minimum (a dark fringe) is produced when light from the two slits arrive out of phase by exactly one-half of the cycle. For example, The first wave would be at peak while the second would be at a crest when they arrive at the screen. That happens when the path difference is an integer multiple of wavelength plus one-half of the wavelength: $\displaystyle \text{Path difference} = \left(k + \frac{1}{2}\right)\cdot \lambda$ .

<h3 /><h3>Maxima</h3>

The path difference is at a minimum (zero) at the center of the screen between the two slits. That's the position of the first maximum- the central maximum, a bright fringe where $k = 0$ in $\text{Path difference} = 0$ .

The path difference increases while moving on the screen away from the center. The first order maximum is at $k = 1$ where $\text{Path difference} = \lambda$ .

Similarly, the second order maximum is at $k = 2$ where $\text{Path difference} = 2\, \lambda$ . For the light in this question, at the second order maximum: $\text{Path difference} = 2\, \lambda = 2 \times 575\; \rm nm = 1.15\times 10^{-6}\; \rm m$ .

Central maximum: $k = 0$ , such that $\text{Path difference} = 0$ .
First maximum: $k = 1$ , such that $\text{Path difference} = \lambda$ .
Second maximum: $k = 2$ , such that $\text{Path difference} = 2\, \lambda$ .

<h3>Minima</h3>

The dark fringe closest to the center of the screen is the first minimum. $\displaystyle \text{Path difference} = \left(0 + \frac{1}{2}\right)\cdot \lambda = \frac{1}{2}\, \lambda$ at that point.

Add one wavelength to that path difference gives another dark fringe- the second minimum. $\displaystyle \text{Path difference} = \left(1 + \frac{1}{2}\right)\cdot \lambda$ at that point.

First minimum: $k =0$ , such that $\displaystyle \text{Path difference} = \frac{1}{2}\, \lambda$ .
Second minimum: $k =1$ , such that $\displaystyle \text{Path difference} = \left(1 + \frac{1}{2}\right)\cdot \lambda$ .

For the light in this question, at the second order minimum: $\displaystyle \text{Path difference} = \left(1 + \frac{1}{2}\right)\cdot \lambda = \left(1 + \frac{1}{2}\right)\times (575\; \rm nm) \approx 8.63\times 10^{-7}\; \rm m$ .

25.16 what is the reaction product of acetic acid and ethylamine at room temperature?

Ne4ueva [31]

The ammonium salt of acetic acid is the reaction product of acetic acid and ethylamine at room temperature

<h3 /><h3>What is acetic acid ?</h3>

Acetic acid is a monofunctional carboxylic acid containing two carbon atoms. It acts as a protein solvent, food acidity regulator, antibacterial food preservative. It is a conjugate acid of an acetate.

Acetic acid is used in the production of acetic anhydride, cellulose acetate, vinyl acetate monomer, acetic ester, chloroacetic acid, plastics, dyes, insecticides, photographic chemicals, and rubber. Other commercial uses include the production of vitamins, antibiotics, hormones, organic chemicals, and as a food additive. Typical concentrations of acetic acid found naturally in foods are 700 to 1200 milligrams/kg (mg/kg) in wine, up to 860 mg/kg in aged cheeses, and 2.8 mg/kg in aged cheeses. fresh orange juice.

If you hit another object with your vehicle, your _______ will be slowed or stopped by the force of impact caused by that object

BaLLatris [955]

Answer:

Speed

Explanation:

If a vehicle hit any other object then its speed will slow down or some time the vehicle will stop its depends on the force exerted by other object on the vehicle.

The change in speed of vehicle is due to momentum because momentum is always conserved. So to conserve the momentum the speed of the vehicle decreases because after hitting the overall mass is increases.
