How do you find the fundamental frequency on a calculator? Fundamental frequency is calculated using the formula f = v/2*L where v is the speed of the sound wave, and L is the length of a tube or device the wave is traveling through. How do you find the fundamental frequency with length? Wave Velocity […]

Are glasses concave? Concave lenses are used in eyeglasses that correct nearsightedness. Convex lenses are used in eyeglasses for correcting farsightedness, where the distance between the eye’s lens and retina is too short, as a result of which the focal point lies behind the retina.

Why is geocentric model wrong? The first big problem with the geocentric model was the retrograde motion of planets like Mars. His model has the planets moving around the Sun in circular orbits. This can explain retrograde motion, but his model doesn’t fit all the planetary position data that well. Why is the geocentric model […]
