Answer:
Two beams (that we could think as sinusoidal waves) face destructive interference at a point P, if at that point one of the waves is in a peak, and the other wave is in a through, so when we add them, the waves will "cancel" each other (thus, we have destructive interference)
The case of constructive interference happens when at point P we have two peaks or two throughs, so the waves add up.
If both waves started at the same point and with the same phase and both traveled the same distance, they will always have constructive interference. But if the waves traveled different distances, the constructive interference will happen at points where the path difference of the waves is an integer multiple of the wavelength (remember that the distance between a peak and the next one is the wavelength).
If two beams of coherent light start at the same point and are in phase, then we will have the maximum of destructive interference at a point P if the path difference is exactly half of the wavelength (or (n/2) times the wavelength, with n an odd integer), this happens because the distance between a peak and the next thtough is exactly half of the wavelength.
Then we can conclude that the path difference between the two beams is of the form:
(n/2)*λ
where:
n = odd number = (2*k + 1) with k an integer.
λ = wavelength of the beams.
Hydrogen = 1
oxygen = 8
but then remember the 2

Greater the collision
Explanation:
The greater the speed of gas particles in the containers, the greater the collision of gases with the container and between themselves.
- The speed of gas molecules increases when their kinetic energy increases.
- This causes a surge in collision between the particles and the wall of the container.
- A gas is composed of large number of molecules moving at different speeds.
- When the temperature of gases are increased, they gain more kinetic energy and their speed will increase.
- This leads to an increase in effective collision between gas particles.
