Answer:
1.7x10^8 Hz
Explanation:
Frequency could be explained as the number of occurrences of a repeating event at a time
Given:
wavelength = 1.8 meters
The frequency f of the waves can be calculated using f = c / λ
Where c (m/s) is the speed of the wave
λ (m) is the wavelength
Speed c= 3*10^8 m/s
Frequency f= 3*10^8 /1.8
Frequency= 1.7x10^8 Hz
Therefore,the frequency of waves from a radar detector is 1.7x10^8 Hz
Answer:
This would be a phase change
Explanation:
Since the diffrent phases solid,liquid,gas are changing to other phases.
Sorry for the bad explanation.
Answer:
z≅3
Atomic number is 3, So ion is Lithium ion (
)
Explanation:
First of all
v=f*λ
In our case v=c
c=f*λ
λ=c/f
where:
c is the speed of light
f is the frequency
Using Rydberg's Formula:
Where:
R is Rydberg constant=
z is atomic Number
For highest Energy:
n_1=1
n_2=∞
z≅3
Atomic number is 3, So ion is Lithium ion ()
Answer:
The correct statement should be The energies of electron are <em>quantized</em> when <em>they are bounded to an atom.</em>
In Quantum Mechanics The term Quantization used to measure the physical entities having certain discrete value. When we say energies of electron are <em>quantized</em> <em>that means it have some specific values</em> that are allowed, that is not continuous range of values.
