If the angle between incident ray and reflected ray is 70 degrees, then what is the angle of reflection

hey buddy here is your answer

* the angle between the incident ray and the reflected ray is the sum of the angle of incidence and the angle of reflection.

*the angle is incidence is equal to the angle of reflection.

* Both, the angle of incidence and the angle of reflection, are equal to half the angle between the incident ray and the reflected ray.

therefore, angle of incidence=70/2=35

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.
