Sensory nerves contaim only sensory fibres that is which bring impulses from the receptors to the brain ir the spinal cord. Example: optic nerve arising from the eye and ending in the brain.
Motor neves contain only motor fibre that is which carry the impulse from the main nervous system to an effector( muscle or gland).
