Answer from: Emorej22

The distance between the slits is about 1.8 × 10⁻² mm

$\texttt{ }$

Further explanation

Let's recall the Young's double-slit formula as follows:

$\boxed {d \sin \theta = n \lambda }$

where:

d = distance between the slits ( m )

θ = angular distance

n = order number

λ = wavelength ( m )

Let us now tackle the problem!

$\texttt{ }$

Given:

angular distance = θ = 7.0°

frequency of the light = f = 5.4 × 10¹⁴ Hz

order number = n = 4

speed of light = v = 3 × 10⁸ m/s

Asked:

distance between the slits = d = ?

Solution:

$d \sin \theta = n \lambda$

$d \sin \theta = n \frac{v}{f}$

$d = \frac{ nv } {f \sin \theta}$

$d = \frac { 4 \times 3 \times 10^8 } { 5.4 \times 10^{14} \times \sin 7.0^o }$

$d \approx 1.8 \times 10^{-5} \texttt{ m}$

$d \approx 1.8 \times 10^{-2} \texttt{ mm}$

$\texttt{ }$

Conclusion:

The distance between the slits is about 1.8 × 10⁻² mm

Acetic acid /əˈsiːtɪk/, systematically named ethanoic acid /ˌɛθəˈnoʊɪk/, is a colourless liquid organic compound with the chemical formula ch3cooh (also written as ch3co2h or c2h4o2). when undiluted, it is sometimes called glacial acetic acid. vinegar is no less than 4% acetic acid by volume, making acetic acid the main component of vinegar apart from water. acetic acid has a distinctive sour taste and pungent smell. in addition to household vinegar, it is mainly produced as a precursor to polyvinyl acetate and cellulose acetate. it is classified as a weak acid since it only partially dissociates in solution, but concentrated acetic acid is corrosive and can attack the skin.acetic acidnamespreferred iupac nameacetic acidsystematic iupac nameethanoic acidother namesvinegar (when dilute); hydrogen acetate; methanecarboxylic acid[1][2]identifierscas number64-19-7 3d model (jsmol)interactive image3dmetb00009 reference506007chebichebi: 15366 chemblchembl539 chemspider171 drugbankdb03166 echa infocard100.000.528ec number200-580-7e numbere260 (preservatives)gmelin reference1380iuphar/bps1058keggd00010 meshacetic+acidpubchem cid176rtecs numberaf1225000uniiq40q9n063p un number2789inchiinchi=1s/c2h4o2/c1-2(3)4/h1h3,(h,3,4) key: qtbsbxvteameqo-uhfffaoysa-n smilescc(o)=o

An important dimensionless parameter concerned with very high-speed flow is the mach number, defined as v/c, where v is the speed of the object such as an airplane or projectile, and c is the speed of sound in the fluid surrounding the object. for a projectile traveling at 1170 mph through air at 50 ˚f and standard atmospheric pressure, what is the value of the mach number?

We will use a video to study faraday’s law of electromagnetic induction by analyzing the induction that occurs due a coil of copper wire sliding along an air track that passes through an external magnetic field. specifically, we will: examine some of the main principles behind faraday’s law. apply lenz’s law to determine the direction of the induced emf. take measurements of the induced emf from the voltmeter as the coil passes into and out of the external magnetic field. use the horizontal scale provided to determine the speed of the coil. calculate the magnetic field induced in the coil as it passes into and out of the external magnetic field.
