Why is a Spherometer called so? A spherometer basically is a precision instrument to measure very small lengths. Its name reflects the way it is used to measure the radii of curvature of spherical surfaces. Where is Spherometer used? The Spherometer is a device use in measuring the radius of curvature of a spherical surface. […]
Can you make magnets spin forever?
Can you make magnets spin forever? As the energy in magnets lasts for many years, the wheel is able to rotate and keep on spinning without the need to ever stop, thus the motion of the spinning wheel creates power for many years. This is what makes a magnetic powered generator into a perpetual generator. […]
What is gamma decay stopped by?
What is gamma decay stopped by? Gamma radiation is the most penetrating. It can penetrate air, paper or thin metal. It may only be stopped by many centimetres of lead or many metres of concrete. What is the strongest ionizing radiation? Alpha particles What is the most dangerous type of ionizing radiation? Gamma rays are […]
Is wavelength directly proportional to frequency?
Is wavelength directly proportional to frequency? Wavelength is commonly designated by the Greek letter lambda (λ). Assuming a sinusoidal wave moving at a fixed wave speed, wavelength is inversely proportional to frequency of the wave: waves with higher frequencies have shorter wavelengths, and lower frequencies have longer wavelengths. Which Colour Has Highest intensity? violet What […]
Why does sky turn pink?
What does refractive index indicate?
What does refractive index indicate? Refractive index, also called index of refraction, measure of the bending of a ray of light when passing from one medium into another. Refractive index is also equal to the velocity of light c of a given wavelength in empty space divided by its velocity v in a substance, or […]
Which sense would be most difficult to live without?
How do you tell the difference between independent and dependent variables?
How do you tell the difference between independent and dependent variables? The independent variable is the one the experimenter controls. The dependent variable is the variable that changes in response to the independent variable. The two variables may be related by cause and effect. If the independent variable changes, then the dependent variable is affected. […]
How do we use reflection in everyday life?
How do we use reflection in everyday life? Applications of Reflection of Light in Daily Life Meters like ammeters and voltmeters use a mirror to avoid parallax error. The wing and rear-view mirrors of a car are made of a convex and a plane mirror respectively. A microscope uses a mirror to reflect light to […]
Which atom will never form a double bond?
Which atom will never form a double bond? The double bond rule states that chemical elements with a principal quantum number greater than 2 for their valence electrons (period 3 elements and lower) tend not to form multiple bonds (e.g. double bonds and triple bonds) with themselves or with other elements. Can carbon form a […]
