Inverse variation can be applied in physics. The relationship between wavelength and frequency of light are closely related. The equation Av=c where A is the wavelength, v is the frequency and c is the speed of light represents the relationship between wavelength and frequency of light. When written as an inverse variation equation, we can write Question 3: = or we can write In this formula, which variable represents the constant of variation k? Is it logical that this variable represents the constant of variation? Explain your answer. Answer:
