The conformal β− change of Finsler metric L(x, y) is given by L∗(x, y) = eσ(x) f (L(x, y), β(x, y)), where σ(x) is a function of x, β(x, y) = b i (x)yi is a one-form on the underlying manifold Mn , and f(L(x, y), β(x, y)) is a homogeneous function of degree one in L and β. Let Fn and F∗n be Finsler spaces with metric functions L and L∗ respectively. In this paper we study the hypersurface of F∗n and find condition under which this hypersurface becomes a hyperplane of first kind, a hyperplane of second kind and a hyperplane of third kind. In this endeavour we connect quantities of F∗n with those of Fn . When the hypersurface of F∗n is a hyperplane of first kind, we investigate the conditions under which it becomes a Landsberg space, a Berwald space, or a locally Minkowskian space.
