590-620nm. Identical to orange.
The difference between brown and orange is the brightness level, and since the eyes have an automatic brightness adjustment, brightness levels only appear in context.
Light becomes a darker variant if there's brighter light around and vice versa. Shine brown/orange light into a dark room, and it will appear orange. Shine the same light into a brighter context, and it will be brown.
It's exactly the same thing as e.g. dark blue or light blue. Both share the exact same wavelength, and their brightness becomes apparent in context.
If you've ever been to a cinema and you saw anything brown or orange on screen, you have seen the effect. If you have ever seen a dim conventional light bulb in a bright room, you have seen it too.
Brown has just as much a wave length as orange, because it's the same color.
