(a) Wavelength of the light in the vaccum is 5.17 X 10⁻⁷m

(b) Wavelength of light in glass is 3.40 X 10⁻⁷m

Given;

Frequency (λ) : 5.80 X 10¹⁴ Hz

Refractive index (η) = 1.52

(a) Wavelength of light λο = C/f

where, c = speed of light

f = frequency

                                      λο = (3 X 10⁸ m/s)/5.8 X 10¹⁴ Hz

                                      λο = 5.17 X 10⁻⁷

Wavelength of the light in the vaccum is 5.17 X 10⁻⁷m

(b) Wavelength of light in glass λ = λο/η

where, η = Refractive index

               λ = λο/η = (5.17 X 10⁻⁷m) X 1.52 = 3.40 X 10⁻⁷m

Therefore, wavelength of light in glass is 3.40 X 10⁻⁷m

The distance between the two crests or troughs of the light wave is known as the wavelength of light. Using the Greek letter lambda (λ), it is identified. As a result, wavelength refers to the separation between one wave's crest or dip and the following wave.

Visible spectrum: The part of the electromagnetic wave that can be observed by human vision is known as the visible spectrum. The visible spectrum in the electromagnetic spectrum spans from the infrared to the ultraviolet regions. Between the infrared and ultraviolet wavelength ranges is where the visible light falls. From 400 nanometers (violet) to around 700 nanometers, the human eye can sense light (red). Other electromagnetic radiations are either outside the range of biological function or are too small or huge to be detected by the human eye.

A particular automobile with an initial speed of 65 km/h will come to 120 km/h in 8.49 s

The formula for Uniformly varied rectilinear motion (UVRM) and procedure we will use to solve this exercise is:

t = (vf - vi) /a

Where:

Information about the problem:

By converting the velocity from km/h to m/s, we get:

65 km/h * (1000 m / 1 km) * (1 h / 3600 s) = 18.056 m/s

120 km/h * (1000 m / 1 km) * (1 h / 3600 s) = 33.33 m/s

Applying the time formula, we have:

t = (vf - vi) /a

t = (33.33 m/s - 18.056 m/s) / 1.8 m/s2

t = 15.274 m/s /  1.8 m/s2

t =  8.49 s

Next, for point B, the distance is equal to,

Dyz = | 3 | = 3 units

Lastly, for point C, the distance is equal to,

Dyz = | 2 | = 2 units

Since point C has the smallest distance to the yz -plane, this point is closest to the yz-plane.

Photons per second, n, would enter an aperture of area a = 5cm2 located a distance d = 4 m from the light bulb, N = 6.4886 *10¹²

A particle representing a quantum of light or other electromagnetic radiation. A photon carries energy proportional to radiation frequency but has a zero rest mass.

A photon is a particle of light defined as a discrete bundle (or quantum) of the electromagnetic (or light) energy. Photons are always in the motion and, in a vacuum (a completely empty space), have a constant speed of light to all observers.

Assumption:

2.5% of electrical energy is converted into the light.

Power = 100W

So, to calculate energy of light per second, we simply multiply 100 to 2.5%

E = 100 * (2.5/100) = 2.5J

To calculate number of photons, we have the formula

N = (2.5 * λ)/h c

Now, using distance of 5m, we find area of the sphere using formula 4λR²

A=4*3.14*4² = 314m²

Now, to determine the number of photons passing through area of 3cm² or 0.0003m²

N = (5*10⁻⁴/314)*[(2.5*λ)/h c ]

Now by putting values we get,

N = (5*10⁻⁴/314)*[(2.5*540*10⁻⁹)/((6.626*10⁻³⁴J.s)(5*10⁸))]

Explanation:

It is the true statement, that if we double the force acting on a body, the acceleration will double.

In terms of both speed and direction, acceleration is the rate at which velocity varies over time. Acceleration refers to the change in speed or direction of an item or point travelling straight forward. Due to the constant change in direction, motion on a circle accelerates even while the speed is constant. Both impacts help to accelerate all other types of motion.

In order to be a vector quantity, acceleration must have both a magnitude and a direction. As a vector quantity, velocity is also. A time interval's velocity vector change divided by that interval's duration is the definition of acceleration.

Acceleration is the rate of change in a moving object's speed and direction over time. When something moves faster or slower, it is considered to be accelerating. Motion on a circle accelerates even while the speed is constant because the direction is always changing.

Any change in an object's velocity causes an acceleration, whether it be an increase in speed (what most people refer to as acceleration), a decrease in speed (also known as a deceleration ), or a change in direction (called centripetal acceleration ).

The correct answer No the velocity is not zero anywhere For an object being launched at ground level at a tilted non-zero initial velocity, and horizontal or vertical components of the velocity is zero at maximum height .

Because velocity is a vector (it has magnitude and direction), the overall velocity of an object can be calculated by adding the x and y components: v2 = vx2 + vy2. Meters are used to express horizontal and vertical distances (m). The horizontal velocity component (vx) describes the effect of velocity on horizontal displacement of the projectile.

The vertical velocity component (vy) describes the effect of velocity on vertical displacement of the projectile. The vertical component of a projectile's velocity is momentarily zero (vy = 0 m/s) when it reaches maximum height. The horizontal component of its velocity, however, is not zero.
