Which three phenomena occur during a double-slit experiment and support the wave model of light? A. The light passes through the slit
B. Bright areas appear on the screen
C. Light bends around the edges of the slit
D. Dark areas appear on the screen
Answers
The three phenomena occur during a double-slit experiment and support the wave model of light is bright areas appear on the screen, light bends around the edges of the slit, dark areas appear on the screen. Therefore, option B, C and D are correct.
What is double slit experiment ?
The double-slit experiment, which was conducted to study the characteristics of light in the eighteenth century, has subsequently been found to illustrate the duality of photons as well as the ideas of superposition and quantum interference.
It implies that things we refer to as "particles," like electrons, in some ways mix the traits of both particles and waves. That is quantum physics' renowned wave-particle duality.
The three phenomena occur during a double-slit experiment and support the wave model of light is bright areas appear on the screen, light bends around the edges of the slit, dark areas appear on the screen.
Thus, option B, C and D are correct.

All the statement is true about the elements of group 16.
What is Groups and Periods in Periodic table ?
In periodic table 18 vertical column are present which is called groups which are arranged from left to right in the periodic table.
In periodic table 7 horizontal rows are present which is called periods.
Now lets check all options one by one.
Option (A): They need two electrons to complete their octet.
In periodic table Group sixteen have 6 elements in its valence shell. Group 16 elements needed two electrons to complete the octet valency. The valency of group 16 elements is 2. So it is true about the group 16 elements.
Hence, it is incorrect option.
Option (B): They have an oxidation number of 2-
Group 16 show variable oxidation state that is -2, +2, +4 and +6. So the statement is true.
Hence it is incorrect option.
Option (C): They have an oxidation number of 2+.
Group 16 show variable oxidation state that is -2, +2, +4 and +6. So the statement is true.
Hence it is incorrect option.
Option (D): They have six valence electrons
Group 16 elements are called Chalcogens. They have 6 valence electron so they achieve noble gas configuration. So it is true statement.
Hence, it is incorrect option.
Thus, from the above conclusion we can say that all the statement is true about the elements of group 16.

Answer: First we have to understand that the normality of a solution is the gram equivalent weight of a solute per liter of solution. To find it we simply will have to have the necessary data to see the balanced equation.
I hope it helps, Regards.
Eg: H2SO4 + Na2OH ⇒ Na2SO4 + 2H2O
H2SO4 can neutralize 2 M of NaOH so equivalent of H2SO4 is 2 and that of NaOH is 1
For ions, equivalent is the number of charge and for acids or bases it is the acidity or basicity.
Equivalent weight is weight of 1 equivalent of any compound
