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 […]

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 […]

Where do polar easterlies occur? Polar Easterlies- Polar Easterlies can be found at the north and south poles and they are cold and dry because of where it is located, which is at high latitudes. This type of wind system forms when cool air, at the poles, and then transfers to the equator. What is […]
