Answer:
f = 0.6× 10¹⁶ Hz
Explanation:
Given data:
Wavelength of radiation = 5.00 × 10⁻⁸ m
Frequency of radiation = ?
Solution:
Formula:
Speed of light = wavelength × frequency
speed of light = 3 × 10⁸m/s
Now we will put he values in formula.
3 × 10⁸m/s = 5.00 × 10⁻⁸ m × f
f = 3 × 10⁸m/s / 5.00 × 10⁻⁸ m
f = 0.6× 10¹⁶ s⁻¹
s⁻¹ = Hz
f = 0.6× 10¹⁶ Hz
Answer:
Explanation:
The expression for the deBroglie wavelength is:
Where,
is the deBroglie wavelength
h is Planck's constant having value 
m is the mass of electron having value 
v is the speed of electron.
Given that v = 
Applying in the equation as:
Keeping your arm straight in front of you, you rotate 90° to your left, and see the left side of the circle lit while the right side is dark. Half the ball is still lit up, but you can see only part of the lit area. As you continue to rotate, you see a different amount of the ball.
Yes, 50 pennies plus 50 pennies equals 100 pennies minus 50pennies equals 50 pennies.
