Why electromagnetic wave can travel in vacuum?
Why electromagnetic wave can travel in vacuum? The propagation of electromagnetic waves either in a certain medium or in vacuum is due the the mutual changes between the electric and magnetic field. These variations in electric and magnetic fields fields lead to the transfer of the energy which is carried by the EM wave. What […]
Why are graduated cylinders not accurate?
Why are graduated cylinders not accurate? Similar to cylinders, beakers are graduated with volume measurements. In that case, why is a graduated cylinder more accurate than a beaker? The volume marks on a beaker are only approximate values, and therefore only provide whole numbers. What is a graduated cylinder is used to measure? Liquid volume […]
Does wavelength change with distance?
Does wavelength change with distance? As light travels away from a galaxy, the Universe is continually expanding, meaning that the distance the light needs to travel is continually increasing as well. As space stretches out underneath a beam of light, its wavelength increases, and its energy decreases. Does frequency increase with distance? The frequency of […]
How often is the weather wrong?
How often is the weather wrong? The Short Answer: A seven-day forecast can accurately predict the weather about 80 percent of the time and a five-day forecast can accurately predict the weather approximately 90 percent of the time. However, a 10-day—or longer—forecast is only right about half the time. Why are weather predictions so inaccurate? […]

Is vaporization and evaporation the same thing?
Is vaporization and evaporation the same thing? Vaporization is defined as the transitional phase of a compound or an element and it occurs during the boiling or sublimation process. Evaporation is nothing but a type of vaporization which mostly occurs at temperatures below the boiling point. What is vaporization short answer? Vaporization, conversion of a […]
Why do scientists believe the Abert and Kaibab squirrels are examples of speciation?
Why do scientists believe the Abert and Kaibab squirrels are examples of speciation? Explain why scientists believe the Abert’s and Kaibab squirrels are examples of speciation. -The Kaibab Squirrel gives us one nice example of evolution occurring due to geographic isolation. One population of squirrels had become two separate populations that could no longer interbreed, […]
