What happens when two waves meet

1 answer:

4 0

Wave interference is the phenomenon that occurs when two waves meet while traveling along the same medium. The interference of waves causes the medium to take on a shape that results from the net effect of the two individualwaves upon the particles of the medium.Hope this help!

What happens to energy as frequency increases on the electromagnetic spectrum?

gladu [14]

As a wavelength increases in size, its frequency and energy (E) decrease. From these equations you may realize that as the frequency increases, the wavelength gets shorter. ... Mechanical and electromagnetic waves with long wavelengths contain less energy than waves with short wavelengths.

Recall that force is a change in momentum over a change in time, the force due to radiation pressure reflected off of a solar sa

Zarrin [17]

Answer:

magnitude of the pressure on the sail in the vicinity of Earth’s Orbit= $\frac{2I}{c}$

Explanation:

The momentum of a photon is:

p = E/c

E = the photon energy

c = the speed of light.

take the time derivative (gives the force)

F = dp/dt = (dE/dt)/c

F = 2(dE/dt)/c (is doubled for complete reflection of the light)

Intensity has the units of energy per unit time per unit area

= I

then,

Force/unit area = 2I/c

magnitude of the pressure on the sail in the vicinity of Earth’s Orbit= $\frac{2I}{c}$

How can the distance between the first bright band and the central band be increased in a double-slit experiment?

Strike441 [17]

Answer:

Decrease the slit separation, increase the distance of the screen from the slits, and increase the wavelength.

Explanation:

The distance $y$ from the central band to the first bright band is given by

$y = \dfrac{ \lambda D}{d}$

where $\lambda$ is the wavelength of light (or any particle), $D$ is the distance to the screen, and $d$ is the slit separation.

From this equation we see that, by increasing the wavelength $\lambda$ , increasing the distance from the screen $D$ , and decreasing the slit separation $d$ , we increase the distance between the first bright band and the central band.

Therefore, the 2nd choice "<em>Decrease the slit separation, increase the distance of the screen from the slits, and increase the wavelength.</em>" is correct.

A drowsy cat spots a flower pot that sails first up and then down past an open window. The pot was in view for a total of 0.56 s

liberstina [14]

Answer:

$h = 0.028 m$

Explanation:

As we know that

$d = \frac{v_2 + v_1}{2} t$

here we have

$1.95 = \frac{v_2 + v_1}{2}(0.56)$

$v_2 + v_1 = 6.96$

also we know

$v_2 - v_1 = at$

$v_2 - v_1 = (9.81)(0.56)$

$v_2 - v_1 = 5.49$

so we have

$v_2 = 6.23 m/s$

$v_1 = 0.74 m/s$

so the height above window is given as

$v_f^2 - v_i^2 = 2 a d$

$0.74^2 - 0 = 2(9.81)h$

$h = 0.028 m$

guajiro [1.7K]

B, C, and D.

Solar energy is green energy, it wouldn't contribute to global warming. However some places of the world don't receive as much sunlight (the poles) and at night you don't receive as much sunlight either. Solar energy is also very expensive to farm.
