3. Direction of Bending When light passes into a more dense material (in this case, water), it bends away from the surface between the 2 materials. The light entering the glass of water is called the incident ray, and the light traveling through the water is the refracted ray. 4. Diffraction  Light can bend around corners or spread out when passing through a narrow slit or encountering an edge. More specifically when applied to light, diffraction of light occurs when a light wave passes by a corner or through an opening or slit that is physically the approximate size of, or even smaller than that light’s wavelength. The amount of bending depends on the relative size of the wavelength of light to the size of the opening. Splitting of white light into the constituent colour components of white light is one form of diffraction Example: CD/DVD colors: The shiny surface of a CD or DVD has microscopic grooves etched onto it. When light hits these grooves, it diffracts and creates the rainbow-like pattern you see. The grooves act like a diffraction grating, separating the light into its component colors. 5. Scattering Scattering of light is the phenomenon in which light rays deviate from their original path upon striking an obstacle like dust, gas molecules, or water vapors. Example: Blue colour of the sky: Out of the seven components present in sunlight, blue colour is scattered the most by the particles present in the atmosphere and hence, the sky appears blue. How is Diffraction of light different that Scattering? Scattering is the ability of particles to absorb light and scatter it in all directions while Diffraction is the bending of light when it encounters an obstacle or an opening.

Dispersion It is this process of white light splitting into its constituent colours. When white light is transmitted through a prism, it is split into seven component colours. Example: A rainbow is an example of white light dispersion. A large number of tiny droplets of water remain hanging in the air shortly after the rain. Each drop acts as a tiny prism. When sunlight strikes these droplets, it divides into seven distinct colours. A continuous band of seven colors is formed by the scattered light which we call a rainbow. 7. Interference Light waves can interact and either amplify or cancel each other out depending on their relative phases. This principle is used in holography and thin-film coatings. 8. Polarization Light waves can vibrate in different orientations. Polarization filters selectively allow light waves with a specific orientation to pass through.  9. Speed of Light The rate at which the light travels in free space is called the Speed of light. Light travels slightly slower through water, as water is more dense than air.

The prefix "milli-" means one thousandth, so 1 millimeter is equivalent to one thousandth of a meter (0.001 meters). The prefix "centi-" means one hundredth, so 1 centimeter is equivalent to one hundredth of a meter (0.01 meters).

When light travels from one medium (e.g., air) to another (e.g., water), it bends due to a change in its speed. This phenomenon is termed as refraction of light. It is used in lenses to focus or diverge light.

Optical

Use the millimeters to centimeters converter below to convert your length measurements. Enter the number of millimeters and the converter will display its equivalent in centimeters.

When light strikes a surface, it bounces back. The angle of reflection is equal to the angle of incidence, governed by the Laws of Reflection. Mirrors use this principle to create our duplicate images.

Optics in Physics: Optics is a fascinating branch of Physics that studies the behaviour and properties of light, including its interactions with matter and the construction of instruments that use or detect it. Optics usually describes the behaviour of visible, ultraviolet, and infrared light. Because light is a type of electromagnetic radiation, and other forms of electromagnetic radiation such as X-rays, microwaves, and radio waves exhibit similar properties.

Light is a form of electromagnetic radiation, existing as a wave and exhibiting particle-like behavior (photons). The Sun is the primary source of light which is utilised by all planets to produce energy.

The centimeter equivalents indicated in the conversion table above can be rounded according to the required precision, whether in terms of significant figures or decimals.

The millimeter and the centimeter are both units of length derived from the meter. The meter is the base unit of length in the International System of Units (the modern form of the metric system and the most widely used system of measurement in the world). The conversion factor (10) facilitates the conversion from one unit of measurement (4.5 millimeters in this case) to another (in centimeters) while maintaining the accuracy of length conversions.

A length of 4.5 millimeters, measured with a ruler, vernier caliper, micrometer, or tape measure, often needs to be converted to centimeters in certain situations. Our conversion calculator is the fastest and most accurate option for converting 4.5 millimeters to centimeters. It can also be used to convert other dimensions, including size, width, height, small distances, thickness, and diameter.

To convert 4.5 millimeters to centimeters, divide 4.5 by the conversion factor 10 (because 1 millimeter is equivalent to 1/10 centimeters). So, to find out what is 4.5 millimeters in centimeters, the calculation is as follows: 4.5 millimeters ÷ 10 = 0.45 centimeters. Therefore, 4.5 millimeters is equal to 0.45 centimeters. From this answer, we can also deduce that there are 0.45 cm in 4.5 mm.

Example: Light rays appear to bend upon entering water. Refraction occurs at the boundary of the two media: air and water. This occurs due to the light slowing down slightly as it changes from the air medium to water.
