Answer:
Frequency = 0.8×10¹⁵ Hz
Explanation:
Given data:
Frequency of photon = ?
Wavelength of photon = 3.75 ×10⁻⁷ m
Solution:
Formula:
Speed of photon = wavelength × frequency
Frequency = speed of photon / wavelength
Now we will put the values in formula.
Frequency = 3 ×10⁸ m/s / 3.75 ×10⁻⁷ m
Frequency = 0.8×10¹⁵ s⁻¹
s⁻¹ = Hz
Frequency = 0.8×10¹⁵ Hz
A non-sandblasted rock could be rough or smooth depending on how it was formed.
A sandblasted rock should be much smoother, since the sand blasts away any rough edges. It will, however, be slightly smaller due to losing those edges.
Answer:
Evolution is the process by which populations of organisms change over generations. Genetic variations underlie these changes
Explanation:
If a trait is advantageous and helps the individual survive and reproduce, the genetic variation is more likely to be passed to the next generation.
