The density of properties will not increase by changing the amount of materials, but only will change if temperature changes because it is the weight <em>per cubic centimeter</em>. For example if you have 20000 grams of gold and its volume is 1040 cubic centimeters, but you also have 550 grams of gold which has a volume of 28.5 cubic centimeters the calculations prove it;
20,000/1040= 19.2 grams per cubic centimeter
as well as 550/28.5= 19.2 grams per cubic centimeter.
Answer-Figure P38.63a
is a three-dimensional sketch of a birefringent crystal. The dotted lines illustrate how a thin, parallefaced slab of material could be cut from the larger specimen with the crystal’s optic axis parallel to the faces of the plate.”
Sorry if it’s it correct
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
