If you think about the colors of the rainbow red, orange, yellow, green, blue, indigo, and violet.  That list of colors shows you the spectrum of visible light and the further right (towards violet) you go the more energy the waves have while the more left (towards red) you go the less energy the waves have.  wavelength and energy are inversely proportional meaning that as energy goes up, wavelength goes down.  therefore the more right (towards violet) you move in the spectrum, the smaller the wavelengths get.

Which are examples of a medium? water and air amplitude and wavelength crests and troughs compressions and rarefactions
umka21 [38]

Answer:

water and air

Explanation:

  • A wave is a transmission of a disturbance from one point or the source to another  point.
  • Transmission of a wave occurs through a material medium or a vacuum. Therefore a medium is the material through which a wave travels through.
  • The medium may be in gaseous form, slid form or liquid form. Therefore water and air are example of medium of transmission of a wave.

If the magnitude of the electric field in air exceeds roughly 3 ✕ 106 n/c, the air breaks down and a spark forms. for a two-di
Vlad1618 [11]

Answer: 39.8 μC

Explanation:

The magnitude of the electric field generated by a capacitor is given by:

E = \frac{V}{d}

d is the distance between the plates.

For a capacitor, charge Q = CV where C is the capacitance and V is the voltage.

C =\frac{\epsilon_o A }{d}

where A is the area of the plate and ε₀ is the absolute permittivity.

substituting, we get

E = \frac{Q}{\epsilon_o A}

It is given that the magnitude of the electric field that can exist in the capacitor before air breaks down is, E = 3 × 10⁶ N/C.

radius of the plates of the capacitor, r = 69 cm = 0.69 m

Area of the plates, A = πr² = 1.5 m²

Thus, the maximum charge that can be placed on disks without a spark is:

Q = E×ε₀×A

⇒ Q = 3 × 10⁶ N/C × 8.85 × 10⁻¹² F/m × 1.5 m² = 39.8 × 10⁻⁶ C = 39.8 μC.

romanna [79]

Answer:

An amorphous solid does not have a definite melting point; instead, it melts gradually over a range of temperatures, because the bonds do not break all at once. This means an amorphous solid will melt into a soft, malleable state (think candle wax or molten glass) before turning completely into a liquid.
