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 […]
What are the 5 examples of sedimentary rocks?
What are the 5 examples of sedimentary rocks? Examples include: breccia, conglomerate, sandstone, siltstone, and shale. Chemical sedimentary rocks form when dissolved materials preciptate from solution. Examples include: chert, some dolomites, flint, iron ore, limestones, and rock salt. What are the 3 main types of sedimentary rocks? There are three different types of sedimentary rocks: […]
Do living organisms defy the second law of thermodynamics?
Do living organisms defy the second law of thermodynamics? We can view the entire universe as an isolated system, leading to the conclusion that the entropy of the universe is tending to a maximum. However, all living things maintain a highly ordered, low entropy structure. Which law of thermodynamics states that absolute zero Cannot be […]
Why is a Spherometer called so?
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. […]
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 effective is tidal energy?
How effective is tidal energy? Tidal turbines are 80% efficient, which is higher than solar or wind energy generators. Barrages reduce the damage of high tidal surges on the land. What are the negatives of tidal energy? Disadvantages of tidal energy Limited installation sites. In order for a tidal power plant to be built, the […]
Is there any time lag between action and reaction?
Is there any time lag between action and reaction? 1 Answer. At any instant in time the action and reaction forces are equal – but since as Sofia pointed out they act on different bodies, that doesn’t mean they “cancel out”: each of the bodies experiences one of the forces and accelerates accordingly. How is […]
