When do you have critical angle?
A critical angle refers to the highest angle the light can possibly refract into or between objects without disappearing. ie = light going from crystal into water, the critical angle is 47degrees.
What is the critical angle for light traveling from water into air?
48.6 degrees
Why do bit rate decrease due to distance?
imagine that your connection in an tube of 10M with a 1degree angle You drop a glass of water in it. That take 10sec. imagine that your connection in an tube of 100M with 1degree angle, You drop a glass of water in it. How long the water take to reach the end ? The data is very comparable to water in drain.... Jean-François Cyr,
What describes the angle between water level and the incline of a water ski ramp?
An acute angle
Why is the water bond angle 104.5 less than the CH4 bond angle 109.5?
in water there are two bond pairs and two lone pairs where as in CH4 there are are four bond pairs nad no lone pair. in ch4 there is only bond pair to bond pair repulsion but in water there are three types of repulsions, lone to lone (greatest repulsion), lone to bond ( lesser repulsion ) and bond to bond ( the least repulsion) , therefore due to the presence of two lone pairs in water the bond pairs are repelled with greater force and they get compressed, reducing the ideal bond angle from 109.5 to 104.5 on the other hand, ch4 has only bond pairs and they dont repel each other that strongly so its angle is greater n its 109.5..
