Answer:
a.96cm
b.77cm
Explanation:
Highest intensity,=19cm
Lowest intensity,=29cm
48cm is the distance for half-wave, wavelength =48cm*2=96cm
b. From a, above we know that half-wavelength is 48cm
Also, the distance of known maximum is 29cm
Next maximum is calculated as:
The next maximum will occur at 77cm
