CREATE TABLE table_28143 ("Camera" TEXT, "Filter" TEXT, "Wavelength" TEXT, "Total exposure time" TEXT, "Exposures" FLOAT)

what is the filter when the wavelength is 222mm (k-band)?
SELECT "Filter" FROM table_28143 WHERE "Wavelength" = '222mm (K-band)'
SELECT "Filter" FROM "table_28143" WHERE "Wavelength" = '222mm (K-band)'
