Optics

LOMO Optics refers to lenses and mirrors produced by the LOMO company in Russia. In telescopes, LOMO Optics are known for their high-quality construction and precision, offering clear and sharp images of celestial objects. Telescopes equipped with LOMO Optics are popular among amateur astronomers for their performance and affordability.

Assuming the "image screen" the question refers to is merely a display of what would be seen through the microscope ocular, a printed letter "e" placed in its normal reading position on a light microscope stage would appear upside down and backwards. This has to do with the shape and position of the two lenses in a compound light microscope. As light rays from the image, moving parallel to each other, pass through the convex objective lens, they are bent toward the middle axis of the lens. The middle axis can be defined as the ray of light that enters the lens's center point at exactly 90 degrees from the lens surface, retaining its original trajectory without modification. Because of this converging trajectory toward this axis, all of the light rays intersect a short distance beyond the lens and continue on their paths, diverging now, until they contact the second convex lens in the ocular of the microscope. As these diverging light rays pass through the second lens, they are bent, as in the first. This time, however, instead of parallel rays bent to intersect, these now divergent rays are bent to be parallel again. At this point, the light that carried the top of the image is now emerging from the second lens at the bottom. In like fashion, all other light rays, except the very center, will have, at this point, inverted their position, thus causing images to appear upside down and backwards.

Reflectivity isn't a property of light, it's a property of the surface that reflects the light. It is the proportion of the energy in an incoming light beam which when it hits the surface is reflected rather than absorbed.

The strength of a sugar solution can be determined by measuring the rotation of polarized light passing through the solution using a polarimeter. Sugar molecules rotate the plane of polarized light, and the degree of rotation is proportional to the concentration of sugar in the solution. By measuring this rotation angle, the strength or concentration of the sugar solution can be calculated.

Optical power refers to the ability of a lens or optical system to converge or diverge light. It is typically measured in diopters (D) and indicates the strength of the lens in focusing light onto the retina. Positive optical power converges light (useful for correcting hyperopia), while negative optical power diverges light (useful for correcting myopia).

No, a fire cannot start through the refraction and conversion of light alone. Fire requires a heat source, fuel, and an oxidizing agent (such as oxygen) to ignite and sustain combustion. Light refraction and conversion do not generate enough heat to start a fire.

Monochromatic means that it has only frequency. Polarized is definition for light which has its electric and magnetic vectors oscillating in a certain way (linearly polarized, elliptically and so on) but it might have many frequencies included. In the same time monochromatic light can be polarized.

White light is a mixture of all colour. Each colour has a different wavelength. When light passes from one medium to another is is refracted (bent). Some wavelengths are refracted more than others, hence the light is split.

terms realated to refraction of light are

* interface

* incident ray

* refracted ray

* point of incidence

*normal

*angle of incidence

* angle of refraction

*angle of deviation

A rainbow is created when sunlight is refracted, or bent, and scattered in raindrops, splitting the light into its different colors. Each color in the rainbow corresponds to a different wavelength of light, creating the beautiful spectrum we see.

Refraction of sunlight by raindrops, the refraction depending upon wavelength to produce the colors

Fiber optics are usually manufactured in long fibers, or string shapes. They can bend and flex like the fibers that make up your clothes, altough they are a bit more rigid and fragile.

The word 'optic' means that it has to do with light. Sometimes a fiber optic cable is called an 'optical fiber'.

Essentially they are like pipes that can guide light along a specific path.

Light bends more through plexiglass than through air because plexiglass has a higher refractive index than air. The refractive index is a measure of how much light is bent as it travels through a medium. Due to the higher refractive index of plexiglass, light is bent more when passing through it compared to air.

The angle of refraction can be calculated using Snell's Law: n₁sin(θ₁) = n₂sin(θ₂), where n₁ is the refractive index of air (1.00), θ₁ is the angle of incidence (35 degrees), n₂ is the refractive index of the plastic (1.49), and θ₂ is the angle of refraction. Plugging in the values gives: (1.00)sin(35) = (1.49)sin(θ₂). Solving for θ₂ gives an angle of refraction of approximately 23.6 degrees.

Yes, Light bends towards the normal when it travels from air to another medium and bends away when going into air from another medium. This can be affected by the angle of incidence and what angle it is.

The refractive index of water is 1.333. Refractive index n = c/v where c is phase velocity of a wave in a vacuum and v is the phase velocity of the wave in the medium. If precision is needed, then more variables come into play and n will change slightly. The temperature of the medium, the frequency of the light, etc... all can come into play.

Firstly, a fiber optic cable transmits light from one end of the fiber optic cable to the other end. You can kind of think of the fiber optic cable as a long tube. The way in which light travels from one end to the other is that it gets reflected off the inside parts of this glass or plastic tube by a physical phenomenon known as: Total Internal Reflection.

Refraction of light only occurs when light travels from one medium to another. For example, when light travels from air to water, from water to air, from water to oil, etc. In other words, in terms of fiber optics, the only way light will get refracted is if it passes through the glass or plastic tube. But if this happened, then the light will exit the fiber optic cable as it travels from one end of the cable to the other end, and the light would not be properly transmitted, defeating the purpose of fiber optics.

In other words, light should be reflective rather than refractive in fiber optics in order for light to be effectively transmitted from one end to the other end of a fiber optic cable.

The sun is all the different wavelengths of light. When all these lights hit water, the change in the speed of the light causes the light to defract away from one another, so you see th rainbow effect

The minimum thickness of the oil film should be equal to half the wavelength of light in the oil medium (because of phase change upon reflection). The formula for minimum thickness is: t = λ / (2 * n), where t is the thickness, λ is the wavelength of light, and n is the refractive index of the medium. Plugging in the values, we get t = 536 nm / (2 * 1.28) ≈ 209.4 nm. So, the minimum thickness of the oil film should be approximately 209.4 nm.

Yes, that is correct. The index of refraction of a material determines how much light will bend as it enters the material. A higher index of refraction means that the light will bend more as it enters the material.

Night Owl Optics typically uses CR123A lithium batteries for their night vision devices. It is important to check the specific model of your device to ensure compatibility with the recommended batteries.

Yes. The mathematical law involving the indicies of refraction n1 & n2 and the angles A1 & A2 as;

n1 Sin(A1) = n2 Sin(A2)

will work regardless of which way the light is traveling. Just associate the variables n & A with the correct medium.

The index of refraction of a substance is inversely proportional to the speed of light in that substance. This means that as the index of refraction of a substance increases, the speed of light in that substance decreases.
