In general, frost damage will turn the new growth brown a few days after the freeze. Here's a closer look at how some trees react: Japanese maples damaged by a late frost may have shriveled, black or brown leaves. Those leaves may fall off and eventually regrow (albeit a bit weaker the second time).

Will my Acer recover from frost damage?

It will probably recover but avoid leaving any water on the leaves if more frost is due. Bit of shock probably. Ladybird's advice is good DYL, and I'd also add that you need to keep it well watered. Your ground looks very dry there.

Can Acers survive frost?

Acers are slow growing deciduous trees/shrubs, and most cultivars are fully winter hardy, however late spring frosts can cause severe damage to emerging foliage.
