A wave travels at a constant speed. How does the wavelength

Physics
1 answer:
Natali [406]3 years ago
4 0

Answer: The wavelength changes by a factor of \frac{1}{2}

Explanation:

The equation of the speed v of a wave is:

v=\lambda f

Where:

v is the speed, that remains unchanged

\lambda is the wavelength

f is the frequency

Isolating \lambda we have:

\lamba=\frac{v}{f}

Now, if we increase the frequency by a factor of 2:

\lambda=\frac{v}{2f}

\lambda=\frac{1}{2} \frac{v}{f} This means the wavelength changes by a factor of \frac{1}{2}

Mashutka [201]

Answer:

Electromagnetic waves are transverse waves, similar to water waves in the ocean or the waves seen on a guitar string. This is as opposed to the compression waves of sound. As you learned in Wave Motion, all waves have amplitude, wavelength, velocity and frequency.Feb 15, 2016

Which one of the following equations correctly represents the process relating to the ionization energy of X?
Naily [24]

Answer:

The correct option is E. X(g) → X⁺(g) + e⁻

Explanation:

The electrons are attracted to the nucleus and it is necessary to provide energy to start them. Then the ionization energy is the energy necessary to pull an electron to a gaseous atom, isolated and in a fundamental state. The electrons in the last shell are the most weakly attracted to the nucleus, so these are the lost electrons.

In this way, the gaseous element is converted to a gaseous cation (positively charged ion).

Taking this definition into account, <u><em>the correct option is E. X(g) → X⁺(g) + e⁻</em></u>
