Explanation Given data: Refer to section 20.3 of 20 th chapter in textbook, the wavelength of red light ( λ red ) is 7.5 × 10 − 7 m , the wavelength of blue light ( λ blue ) is 4 × 10 − 7 m . The wavelength of yellow light is midway between red and blue light. Formula used: Formula to calculate the frequency is, f = c λ (1) Here, c is the velocity of light ( 3 × 10 8 m s ) , λ is the wavelength. Calculation: It is given that the wavelength of yellow light is midway between red and blue light. Therefore, λ = λ red + λ blue 2 (2) Substitute 7.5 × 10 − 7 m for λ red , and 4 × 10 − 7 m for λ blue in equation (2), λ = ( 7.5 × 10 − 7 m ) + ( 4 × 10 − 7 m ) 2 = 5
