person swims 1000 m in the first 400 s, 800 m in the next 400 s and 450 m in the last 200 s. What is the average speed? *
Answers
Answer:
Calculate the angle at which the first dark band and the next bright band
formed in the single slit diffraction pattern of slit width 0.3 mm. Given λ=
5890Å338 m/s) Blue light of wavelength 480rom illuinates diffraction grating. The second order image is formed at an angle of 30° from the central a centimeter are there on the grating? image. How many lines inthe figures have same shape and size are called congruent
