Identification and observation of where and when gaps form in protoplanetary disks is vital for learning about the process of planet formation. We will present simulations of radiative transfer in gas-rich protoplanetary disks with embedded planets that predict and model observable signatures of planet formation. Depending on the mass of the planet, the perturbation may be a local dimple or an annular gap. We will demonstate that these features can already be detected in some nearby gas-rich disks. The appearance of disks with embedded planets varies with wavelength as it ranges from optical through infrared to radio because of optical depth effects. Shorter wavelengths reveal superficial surface features of disks, while longer wavelengths probe deeper in the disk. Confirmation of a planet-induced gap in a disk requires multi-wavelength observations. Imaging of the predicted features of planet formation in disks requires very high spatial resolution, and is currently most feasible in the optical and radio. However, data in the infrared is crucial for constraining the models. Deep gaps created by very massive planets may be detectable in SEDs. Confirmation of a planet-induced gap in a disk requires multi-wavelength observations.
