What is the speed of light in quartz (n=1.54)? Will light travel faster or slower through ruby (n = 1.76) than quartz?

Answers

Answer 1

Explanation:

V=C/n

Quartz: (3×10^8)/(1.54)=1.948×10^8 m/s

The higher the index of refraction the slower light will travel, so light will be slower in ruby.

An object is at rest on a tabletop. Earth pulls downward on this object with a force equal in magnitude to mg. What is the interaction pair to this force

Answers

Answer:

normal contact force

Explanation:

that is the equal and opposite force (as to weight) applied by the table on to the object.

The gravitational force of the earth on the object and the reaction force of the table on the object interact as a pair of forces.

What does gravity mean?

The gravitational force is what pulls things with mass in the same direction. People commonly think about the Earth's gravitational pull. Your body is kept on the ground by this force. Yet, gravity pulls all objects with mass in the same direction.

The gravitational force, or g, is the force that the earth exerts on an object, with g equal to 9.8 m/s2.

The information is ,

Place something on the table.

Now that the item is at rest, a force known as gravitational force pushes it downward from the Earth.

The formula for gravitational force is F = mg, where m is the object's mass.

Moreover, Newton's third law states that every action will always have a corresponding and opposing reaction. When the gravitational force acting between two masses is equal in strength and conducted in the opposite direction, an action and reaction pair is produced.

The reaction force is then given by R = -mg, where m is the object's mass and the negative sign denotes that the force is acting in the opposite direction to that of gravity by earth.

Hence , the interaction pair for gravitational is the reaction force

Two light waves, initially emitted in phase, will interfere constructively with maximum amplitude if the path-length difference between them is:

Answers

Two light waves will interfere constructively if the path-length difference between them is a whole number.

SUPERPOSITION

The principle of superposition state that, when two or more waves meet at a point, the resultant displacement at that point is equal to the sum of the displacements of the individual waves at that point.

Interference of waves can either be constructive, or destructive.

The two light waves, initially emitted in phase, will interfere constructively with maximum amplitude if the path-length difference between them is a whole number of wavelenght 1λ, 2λ, 3λ, 4λ etc

The equivalent phase differences between the waves will be 2[tex]\pi[/tex] or 360 degrees, 4[tex]\pi[/tex] or 720 degrees, 6[tex]\pi[/tex] 1080 degrees etc

Therefore, the two light waves, initially emitted in phase, will interfere constructively with maximum amplitude if the path-length difference between them is a whole number.

If the astronaut throws the 3.20 kg tool with an acceleration of 5.90 m/s2 , what is the magnitude of the acceleration a of the astronaut during the throw

Answers

The magnitude of the acceleration a of the astronaut during the throw of the 3.2 kg tool is determined as (18.88)/m.

Force applied to the tool

Based on Newton's third law of motion, the force applied to the tool by the atronaut is equal to the force exerted on the astronaut by the tool.

Fa = - Fb

where;

Fa is force exterted by the astronautFb is force exterted by the tool

Fa = (3.2 x 5.9)

Fa = 18.88 N

Acceleration of the astronaut

Fa = m x a

where;

m is mass of the astronauta is the acceleration of the astronaut

What is the frequency of light that has a wavelength in water of 600 nm if the refractive index for this light is 1.33

Answers

The frequency of the light with the given wavelength in water is 3.75 × 10¹⁴ Hz.

Wavelength and Frequency

Wavelength is simply the distance over which the shapes of waves are repeated. It is the spatial period of a periodic wave.

Both frequency and wavelength are inversely proportional to each other.

Using the wavelength, frequecy and speed relation;

λ = v / f

Where λ is wavelength, v is speed and f is frequency.

Given the data in the question;

Wavelength in water λw = 600nm = 6.0 × 10⁻⁷mRefraction index u = 1.33Frequency f = ?

We know that frquency in water is the same as frequecy in air, it doesnt change due to medium.

From the expression above, the frequency of the light will be;

λ = v / f

f = Vw / λw

But,

Refractive index u = velocity of light in air / velocity of light in medium ( water )

So,

Vw = ( 3×10⁸m/s × 1 ) / 1.33

Vw = 2.25 × 10⁸m/s

Hence,

f = Vw / λw

f = ( 2.25 × 10⁸m/s ) / ( 6.0 × 10⁻⁷m )

f = 3.75 × 10¹⁴ s⁻¹

f = 3.75 × 10¹⁴ Hz

Therefore, the frequency of light that with the given wavelength in water is 3.75 × 10¹⁴ Hz.
