st. waves r formed when 2waves of same freq. in opp. direction superimpose with each other
light waves when incident perpendicularly on reflecting surface then reflected wave is 180 degree out of phase with incident wave
both when superimpose will produce stationary waves with bright antinodes &dark nodes .

Cause if light never had mass then the whole theory of science related to light would be wrong . That is even in Enstine E=Mass of the light X Velocity . Here i would like to know the mass of light

On a windy day, sometimes it's hard to hear someone talking from a long distance away. From that, I would deduce that sound is affected by air movement. Does that mean, therefore, that if I were to yell upwind from someone on a very windy day, sound will travel faster with a tail wind pushing it along? Would it affect the sound at all?

3. Suppose that you work with 2 cell cultures, X and Y. Culture X has a growth constant of 0.0125 day -1(exponent ni siya sa day) and a present population of 1200. Culture Y has a decay constant of magnitude 0.180 day -1(exponent ni siya) and a population of 1600.

a. Plot a graph of the populations of both cultures over the next days.

b. From your graph, estimate when the populations will be equal.

Something that always confused me was the distance between two points from high above. Suppose you are on a platform 500 miles above the earth, if you take 1 step, wouldn't it be equivalent to miles in distance on land? Whereas if you were on land and take one step, it is only the distance of one step. (2.5-3ft? maybe).

My question is probably similiar to that of missiles/meteors/spaceships and their trajectory for earth. Calculating this sort of thing seems mind boggling. As you move away, everything appears to move to a central point, (shortens) and as you move close, it appears to spread out (lengthens) from that central point. How does science/physics explain it? What's your opinion on this phenomenon?

an electron tube containin three electrodesi is known as triode.in vacuum diode consists of two electrodes namely cathode and anode or plate. we have cloud of negatively charged electrons near the cathode called space charge. in triode i have extra electrode named grid and this grid eliminates space charge around cathode. how it happens? because grid is given negative voltage known as bias . if this bias is negative how the grid removes space charge which is also negative charge.

my question is how triode removes the space charge?
if it is by bias how it happen beause both bias and space charge is negative?
folks please help
