Show that the speed of light is constant over the electromagnetic spectrum Compare: a. X - r rays :?wavelength : 3 nm
MAVERICK [17]

Answer:

CONNECTIONS: WAVES

There are many types of waves, such as water waves and even earthquakes. Among the many shared attributes of waves are propagation speed, frequency, and wavelength. These are always related by the expression vW=fλ. This module concentrates on EM waves, but other modules contain examples of all of these characteristics for sound waves and submicroscopic particles.

As noted before, an electromagnetic wave has a frequency and a wavelength associated with it and travels at the speed of light, or c. The relationship among these wave characteristics can be described by vW = fλ, where vW is the propagation speed of the wave, f is the frequency, and λ is the wavelength. Here vW = c, so that for all electromagnetic waves, c = fλ.

Thus, for all electromagnetic waves, the greater the frequency, the smaller the wavelength

When the pressure is 1.22 atm, a sample of hydrogen gas has a volume of 1.88L. What is its volume if the pressure is increased t
Evgesh-ka [11]

Answer:

1.58 L

Explanation:

Use Boyle's law, which is defined as

p1v1 = p2v2

In this case we're solving for V2 because the rest of the variables are given.

p1 = 1.22 atm

v1 = 1.88L

p2 = 1.45 atm

v2 = ?

p1v1 = p2v2

(1.22 atm)(1.88L) = (1.45 atm)(v2)

v2 = (1.22 atm)(1.88L) ÷ (1.45 atm) = 1.58 L
