How are wavelength, pitch, frequency, and energy all related?

Serggg [28]

Answer:

he word that musicians use for frequency is pitch. The shorter the wavelength, the higher the frequency, and the higher the pitch, of the sound. In other words, short waves sound high; long waves sound low. ... In other words, it sounds higher

The siren on an ambulance is emitting a sound whose frequency is 2450 Hz. The speed of sound is 343 m/s. If the ambulance is sta

lyudmila [28]

Answer:

The wavelength is 0.14 m

Explanation:

Given that,

Frequency = 2450 Hz

Speed of sound = 343 m/s

We need to calculate the wavelength

Using formula of wavelength

$v= f\lambda$

Where, v = speed of sound

f = frequency

Put the value into the formula

$\lambda=\dfrac{v}{f}$

$\lambda=\dfrac{343}{2450}$

$\lambda=0.14\ m$

Hence, The wavelength is 0.14 m

What is a velocity of an object with a momentum of 300 kg m/s and the mass of 100 kg

Brilliant_brown [7]

Answer:

v = 3 m/s

Explanation:

P is the momentum

m is the mass

v is the velocity

P = m•v

300 = 100•v Divide both sides per 100

300/100 = v

v = 3 m/s

In an electron microscope, electrons are accelerated to great velocities. Calculate the wavelength of an electron traveling with

Diano4ka-milaya [45]

Answer:

Wavelength, $\lambda=1.04\times 10^{-13}\ m$

Explanation:

It is given that,

Velocity of an electron, $v=7\times 10^6\ m/s$

Mass of an electron, $m=9.1\times 10^{-28}\ kg$

We need to find the wavelength of an electron. It can be calculated using the De- Broglie wavelength as :

$\lambda=\dfrac{h}{mv}$

$\lambda=\dfrac{6.63\times 10^{-34}}{9.1\times 10^{-28}\times 7\times 10^6}$

$\lambda=1.04\times 10^{-13}\ m$

So, the wavelength of an electron is $1.04\times 10^{-13}\ m$ . Hence, this is the required solution.

Temka [501]

Similar elements with similar properties were in the same groups and periods for instance lithium(Li) and sodium(Na) are alkaline metals and so belong to the same group (that is group 1).Also Hydrogen(H) and Helium(He) both have only one shell or energy level and so belong to the same period.
