Does light travel faster in denser mediums? A denser medium provides more matter from which the light can scatter, so light will travel more slowly in a dense medium. A slower speed means a higher index of refraction, so n2 > n1, as indicated in the image on the left. What is known as optically […]
Why is the gravitational constant important?
Why is the gravitational constant important? The constant, G, determines the strength of Newton’s inverse square law in a particular system of physical units and is, not surprisingly, known as Newton’s constant of gravitation. It is considered to be a fundamental constant of nature. Gravity is also by far the weakest force. Who found the […]

Magnesium, when compared to aluminum, is softer and more expensive, and has the tendency to bend easily. Magnesium, when compared to aluminum, is lightweight and valuable, whereas forged aluminum is stronger. […]
What are the different types of optical instruments?
What are the different types of optical instruments? An optical instrument (or “optic” for short) is a device that processes light waves (or photons), either to enhance an image for viewing or to analyze and determine their characteristic properties. Common examples include periscopes, microscopes, telescopes, and cameras. Is a mirror an optical device? A mirror […]
Can a car run without flywheel?
Can a car run without flywheel? you can start an engine without flywheel But to keep the engine alive you need flywheel because flywheel stores part of energy produced in power stroke and supply energy back to engine during other strokes. Also driving a engine without flywheel will cause fluctuation in power which will lead […]
