    Abstract: In this research, samples of pure polystyrene and Polystyrene 
  (PS) doped with Palm Frond (PF) were prepared using casting method. The effect 
  of addition of Palm Frond (PF) concentration on optical properties of poly styrene 
  have been studied in the wavelength range 200-800 nm. The absorption coefficient, 
  energy gap, refractive index and extinction coefficient have been determined. 
  The results show that the optical constants change with increase of PF concentration.
