Explanation / Answer

o = 456 nm, = 90°. m = 4

d sin = mo

so d = 4o = 4*456 nm = 1824 nm

a) m = 3

d sin = 3, sin = 3/d

sin 1

3/d 1

d/3 = 608 nm

in visible region: 400 nm 608 nm

b) m = 4

d sin = 4, sin = 4/d

if 4/d > 1, then 4th-order maxima are invisible,

d < 4

so d < 4*400 nm = 1600 nm

answer: 224 nm
