The behavior of null geodesics in HSW void spacetimes with a quintessential field for the regular black hole is shown, with orange, green, and blue trajectories. In the left panel, δ_c is varied while keeping γ = 0.1 and ρ_s = 0.1 fixed. The middle panel illustrates the effect of changing γ with δ_c = 0.1 and ρ_s = 0.1. The right panel shows how variations in ρ_s influence f(r) with δ_c = 0.1 and γ = 0.1.
