The distance between successive anti-nodes can be calculated using the formula d=nλ/2, where d is the distance, n is the number of anti-nodes (n=1,2,3,…), and λ is the wavelength. The wavelength can be calculated using the formula λ=c/f, where c is the speed of light and f is the frequency. Substituting the given values, we get λ=0.125 m. Substituting this value in the first formula and taking n=1, we get d=6.25 cm. Therefore, the distance between successive heating anti-nodes in a microwave oven's cavity is approximately 6.3 cm.
