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:
They are averages.
Explanation:
atomic numbers on periodic tables are derived from the average value of all the isotopes of the element. So being averages they are sometimes not integers.
Packing
Explanation:
Ionic crystals are brittle due to the tight packing of their crystals. This provides little to no mobility between one another.
- Brittleness implies having little to no elasticity.
- Ionic crystals are held together by strong crystal lattice forces
- These forces prevents crystals from freely rotating and moving space.
- It holds them rigidly and fixed in place.
- Ionic crystals are hard and held electrostatic forces.
