A student performs a double-slit experiment using a monochromatic light source with a wavelength of 5.00x10⁻⁷ m. The pattern appears on a screen 150 cm away ad the bright fringes are 0.40 cm apart. If the wavelength of the light used is changed to 7.50x10⁻⁷ m, what would the average distance between bright fringes become?
