Can we see wavelengths? More simply, this range of wavelengths is called visible light. Typically, the human eye can detect wavelengths from 380 to 700 nanometers. Does white light exist? White light is actually made of all of the colours of the rainbow because it contains all wavelengths, and it is described as polychromatic light. […]

Why do you look better in the mirror than in pictures? This is because the reflection you see every day in the mirror is the one you perceive to be original and hence a better-looking version of yourself. So, when you look at a photo of yourself, your face seems to be the wrong way […]

What is the effect of pressure in change of state of matter? Changes in presure have very little effect on the volume of a liquid. Liquids are relatively incompressible because any increase in pressure can only slightly reduce the distance between the closely packed molecules. If the pressure above a liquid is increased sufficiently, the […]

What is ∈ called? The symbol ∈ indicates set membership and means “is an element of” so that the statement x∈A means that x is an element of the set A. In other words, x is one of the objects in the collection of (possibly many) objects in the set A. Which are the real […]

How do you solve time problems in physics? To solve for time, divide the distance traveled by the rate. For example, if Cole drives his car 45 km per hour and travels a total of 225 km, then he traveled for 225/45 = 5 hours. How do you solve a physics problem? Focus on the […]

Why didnt Barber kill Torres? The identity of Torres is defined by his being “an executioner,” whereas the barber’s identity is defined by the job that he does.

What is one major difference between plasma and gas and why does that difference exist? They are different and unique from the other states of matter. Plasma is different from a gas, because it is made up of groups of positively and negatively charged particles. In neon gas, the electrons are all bound to the […]
